Summary: If you want a phone for display and not for use ...
Review: The phone looks sleek and has state of the art features. The problem: Poor battery life. It detriorates to a point where the battery lasts less than 20 mins on talk and less than 5 mins on speakerphone. The phone is a nice showpiece to keep in the living room but you should buy another phone to use :). I have exchanged this twice from Siemens. Siemens customer service is very nice. They have sent me replacement batteries twice and exchanged the machine twice. But, the machine has problems so what can you do?

Summary: Not worth the money nor the space saved on your countertop!
Review: (please read the update below)PROS: Fancy looking, fancy feature set, compact
CONS: Expensive, Poor Battery Life, Poor Caller ID functionality, Poor Softkey Response I have had this phone for less than one year. Although it looks fancy, is compact, and advertises a great feature set, it can't be away from the charger for more than 30 minutes. It doesn't even need to be in use for the battery to drain. Example: I use the speakerphone for about 5 minutes. Then I let the phone sit idle on my desk for about 15 minutes. A few minutes into the next call, the low battery beep, which is highly annoying, starts to sound. This has happened on numerous occassions for the past few months. I am basically restricted from using my cordless phone for more than 30 minutes. I have a cheapo lime green V-Tech I received as a gift that can stay off the charger for hours and be fine. The caller ID also doesn't work as well as the phone company provided-caller ID box. I've noticed that the phone company's Caller ID box logs more calls than the Siemens does, and faster! The other thing I don't like is the softkeys. When I want to delete a voicemail message, I may have to press the "Delete" softkey up to three times for it to register. I think Siemens could improve on this functionality. I bought the Siemens not because of fancy features such as room monitoring and voice recognition, but because I didn't want to pay the phone company for an answering service, and I didn't want the additional caller ID and answering machine units cluttering my counter top. I advise those who are interested in this phone for those same reasons to reconsider. UPDATE: I just got off the phone with Siemens customer service. They basically told me that the batteries my phone came with hold some kind of memory in them, yadda yadda yadda. They told me I need to update to a different type of battery: the nickel-hydride metal battery. They used to send these out as a courtesy to customers, but no longer do so and haven't had the batteries for three months. Unlike a previous reviewer, I did not get free battery replacements.

Summary: I'm not disappointed
Review: This is a fine unit. There are tons of features (and despite the contrary views here, very easy to access). I still haven't turned off the telco$ company's voicemail yet to try out the digital answering machine. I especially like having to enter information once, and "downloading" it to the other handset. Now if only everything were Bluetooth...

Summary: Eurotrash
Review: My wife and I bought this phone shortly after having our place remodeled with very high expectations. The phone is nicely styled, has some terrific features and the multiple handset feature really sounded attractive. Unfortunately, the phone was initially delivered with dead batteries -- a harbinger of things to come. We have had to replace our base unit twice in nine months (it shorted out) despite new phone and electrical wiring in the house and surge protection. Dealings with Siemens customer service have proven to particularly frustrating....

Summary: Short battery life
Review: Great features and design except for the battery life. It started out great and has deteriorated to the point that it only lasts about 40 minutes. My sister has the same phone and the same problem. She even exchanged it thru Siemens twice and the same thing.

Summary: Not worth the cost!
Review: I have had this product for a little over a year. It does not hold up well. In addition to being difficult to program, the sound quality is deteriorating and the keypad on all of the handsets have become difficult to use. I sincerely regret having purchased with product.

Summary: Good features, fair to poor sound quality
Review: Th features on this phone are addictive - Multiple ring types, speakerphone on the handset, screen messages on the handset, but the sound quality is poor and there is no handset locator button on the base. When you raise the handset volume, the S/N ratio goes way down (alot of air/hissing in the background). In addition, the sound cuts in and out as you carry on a conversation, almost like a speaker phone would, except you're not on speakerphone. I want to like this phone, but I just can't do it. 3 stars is generous.

Summary: voice recognition is great
Review: I like the voice dialing feature on this. I've always been bad with remembering numbers but can always remember a person's name or face. I guess I'm not a numbers kind of person. In any event, this phone is great. Unlike other cordless phones, this one has a decent range (I can go all over my house without it dropping the call), excellent battery life, and great clarity and always free from interference. My previous 900 mhz cordless phone was always experiencing interference, so this is a great change.

Summary: Review: Siemens 4215 vs. Panasonic XG-TG2730
Review: The Siemens 4215 is not only the worst cordless phone I've ever used, but may be the worst consumer product. This phone looks bad on its own, but comparing it to the Panasonic system I bought to replace it makes it look even worse. This phone has a number of features that sound cool: voice dialing, speakerphones on the headsets, lots of expandability, and a big directory. It does all these things, but it doesn't do any of the simple things well. Battery life is awful (batteries run out just hours after being charged). The caller id call log doesn't work at all: it accurately displays the caller id information for incoming callers, but can't remember any past calls. Many common functions (for example, picking up an extension and joining a conversation or changing the receiver volume) require you to navigate two layers of menus. Finally, switching to an incoming call on call waiting requires holding down the "memo" button for two seconds, not just pressing a flash button like on a normal phone. Half the time I end up hanging up on one of the two callers. Additionally, the receivers break very easily when exposed to just a few drops of water. I don't expect to shower with my cordless phone, but if I'm washing vegetables and pick it up with damp hands, or pick up the phone while still sweating after a run, I expect the phone not to break. I've broken three Siemens phones this way (two phones lost their LCD displays, one lost its speaker). Siemens customer service was unable to diagnose my problems and refused to take back my phones, even after five different requests. I finally gave up and bought a replacement. I've had the Panasonic for just a couple days now, and I'm much happier with it. I'll write a full review of that phone when I've used it longer, but here's a short summary of what I like so far. First, the phone works. No problems with caller id, call waiting, or anything else. Secondly, the voice quality is much, much higher. My only problems with the Panasonic phones are that they interfere IEEE 802.11b networks (set your APs to channel 1 or 11 if you want them to still work), and only have a 50 number directory. The Siemens phones look really tempting... the Gigaset was the first multi-handset system, the Siemens phones have the most features, and the phones are cool looking. However, these phones are expensive, easily breakable, and almost nonfunctional. Don't buy this phone.
