Unacceptable for home use 
2004-03-30
I purchased six of these phones and the four line system. The range is exceptional and that is the only good thing that can be said for this system. Within four days, one phone became defective and it took Engenius four weeks and six phone calls to repair it. They didn't know they'd received it for repairs, said they mailed it back, (they hadn't), and at least four phone calls went unreturned for days at a time. The phone takes a second or two to obtain a line, there is no ability to have specific lines ring on specific phones short of using the voice answering system, which not all home users want to do, the battery life is very short, and the phones will suddenly "crash" and require you to turn them back on. Every few days the main unit need to be powered off and on. The software is very buggy and technical support not acceptable. I would not recommend this system for home use. You will be very unhappy, unless you need exceptional range, there is nothing else to recommend it.
Junk 2004-02-27
Although the range on these things are good, the sound quality is horrible. There's a constant hiss in the background, battery time is low, and the phones are uncomfortable to hold (small and HEAVY). Also, the buttons on the phone are extremly slow to react. When you start dialing you hear the tone about a second later, which is really annoying as you're dialing a number. In short, these phones are poorly built and designed, bad features, and generally not worth it even if they were half the price.
Great range, OK quality 
2003-02-28
I bought this phone because I was tired of trying to get other cordless phones to work in my sprawling house and yard - they didn't have enough range. Specifically I recently tossed the Siemens Gigaset due to poor range.
Well, this phone works admirably - it has more than enough range for a large property with no fade out. The handsets are tough and feel solid (they are really meant for factory or warehouse use). Battery life hasn't been an issue for us at all - in a home you usually keep the handsets in a charging cradle when not in use anyways. Voice quality is as good as the Siemens was. And the fact that it works at 900 Mhz is a bonus since it won't interfere with my wireless Ethernet (802.11) network.
This is an update since I've had these phones for about 6 months now: They aren't perfect. When you put the phone into the cradle to recharge, you have to put it in carefully otherwise it'll look OK, but won't be recharging. Also the recharging contacts are fragile compared to other phones and in fact I have to toss out one of my SN-920's 'cause the contacts got damaged. And the microphone on another SN-920 died. Also, the phones aren't comfortable against your ear.
My ideal phone would have the SN-920's distance with better ergonomics and better recharge contacts. Unfortunately, I don't know of such a phone.
Good for distance, not for quality 
2002-08-29
If you need the long distance, this phone will give it to you but don't expect reliability. We continually have battery problems and as another review said it has it's quirks. The handset is heavy and not very ergonomic. For the money, it's rather disappointing.
EnGenius SN920 Ultra 
2001-12-14
My principal reasons for purchasing the EnGenius SN920 Ultra were:
1) supported multiple remote handsets
2) could be expanded to support multiple incoming lines
3) operated in the 900MHz band
The 900MHz band was a key issue, since I planned to install an IEEE 802.11b RF LAN, which operates in the 2.4GHz band. This ruled out any of the 2.4GHz phone systems, since they would interfere with the phone and vice-versa.
The EnGenius SN920 works fine from a technical standpoint, but there are numerous quirks about the phone, especially with regards to 'human factors' issues:
1) Voice quality is good, but not as good as a Motorola STARtac. This is surprising since the SN920 uses ADPCM digital encoding. Also, the speaker has very poor low frequency response, likely due to the small size of the phone, and is nowhere as good as a traditional corded phone.
2) A very annoying trait is that when you pick up the phone from its cradle, the caller ID info disappears! This forces you to crouch down to view the caller ID, which is inconvenient.
3) When the phone is not in its cradle, you answer it by pressing 'TALK', which is fine. Unfortunately there is no way to configure the phone to require 'TALK' to be pressed when it is picked up from its cradle, so picking up the phone that is already in a cradle versus not in a cradle is *different* and annoying. Half the time, we have to press 'TALK' twice, since you shouldn't press 'TALK' after you pick it up from a cradle. Although this sounds like a trivial nit, it really is a hassle.
4) I would not recommend this phone for older people, especially those who have arthritis. The phone is smaller and heavier than most, but it is too heavy for a moderately infirm person to hold for a long time. The buttons are also harder to push. The phone was designed this way for heavy-duty industrial environments, but it does make it difficult to use if you are 80 years old and have arthritis.
So, keep these issues in mind if you are considering this phone. From a system design standpoint, the ability to add multiple lines and handset is great, and the fact that it operates in the 900MHz is a major plus if you are planning to install a 802.11b RF LAN. (I'm surprised that cordless phone system vendors are not considering this issue more; I've talked to Apple and Siemens and they have confirmed that 2.4GHz phones and 802.11b RF LANs can and do interfere with each other.)
Decent for Long Range 2001-09-18
EnGenius SN-920 Ultra cordless phones are designed to perform as the longest-range cordless phones and 2-way radio systems. Allowing you an incredible range for both telephone and 2-way radio communication, these phones combine Digital Spread Spectrum with Frequency Hopping technology and up to 4 times the power of typical 2.4 GHz phones. EnGenius outdistances all other cordless phones. In office buildings you can expect up to 12 floors of penetration, in warehouse up to 250, 000 square feet can be covered, and on a farm or ranch cover up to 3, 000 acres.EnGenius offers the convenience of direct, handset-to-handset, 2-way radio communication, completely independent of the base unit. This unique feature makes it possible for multiple handsets to remain in contact with each other even in remote areas away from the base unit. And with EnGenius 2-way feature, there is no group chatter or having to push to talk; just use the feature like you use the phone. EnGenius phones are equipped with the type II Caller-ID, Caller-ID with call waiting. This feature will allow you to see who is calling before you answer the call. Type II Caller-ID will enable you to identify whom is calling right from the handset's LCD screen.
Not so EnGenius 2001-09-07
For this kind of money, I'm not impressed. Poor battery life. The headset "compatibility" requires some sort of unavailable adapter in order to work with an ordinary 2.5 mm headset jack. You can't have multiple people on the same call at once. You MUST know the other persons handset number and physically transfer the call to them. The base station randomly clicks on the intercom. It also will click and emit a low-pitched tone that sounds like feedback from something. This is all without receiving a call or picking up a handset or anything.
Crisp, clear, yet odd sound 2001-08-02
I bought this phone for myself and for my mother. She loves it, I like it. I also bought the antenna (note: the antenna doesn't really seem to add much additional distance -- I'd love to see some lab tests proving out the usefullness of this add-on").
It is heavier than any cell phone you might use, yet it does work very well "down the block" in my suburban community.
EnGenius SN920ULTRA 2001-07-07
I started with two base/handset combos, to use at a small office. By far, this has the best range of any cordless I have ever seen, and the two way between handsets is more than convenient. However, having purchased a "multi line phone", it would be nice to have access to both lines - ie. if you are on line one, and line two starts ringing, you must run to another phone to answer the second line, as the handsets are only single line units - not much good halfway across the shop. Also if you have any other electronics on line with them, {fax, computer, another phone, etc.} engenius does not check for line usage {except for its own system} before trying to dial outgoing calls {bad fax or download, interupted data transfer/call} and again you run to a phone to make a call. Not to smart for such a high tech system. Great unit for a single line, would NOT recommend it for multi line use.
Well Built Nokia 6100 series clone 2001-04-09
This phone is almost identical to a Nokia 6100 series phone, which I happen to like. It weighs more and has less battery life, but the size and feel is the same. It is an industrial phone and for its small size feels like a brick. I installed the phone without the external base antenna and received reception about 1/2 mile from my home. I live in a wooded area. The phone battery is a metal hydride and can be recharged without memory problems like nickel cad. I really like this phone. The build quality is outstanding and most of the other cordless phones I've owned just feel flimsy. You can't hold this phone against your head while typing because of it's small size, this along with the battery life are the only reasons I can't rate it 5 stars. The small size is also an advantage, you can fit this phone into the same case as the Nokia 5100/6100 series phones.
