Just don't do it.:
I am not in the habit of giving bad reviews, but I unfortunately have to in this case. I was an early adopter of the system- it was just perfect for the older house we lived in at the time. The fact that the old house had just a couple of phone outlets had been a real problem before I found this system (I bought the 2415). I hauled out my credit card and bought the system and three extra handsets, very expensive. For about two months, things were great. Even my wife, a noted technophobe, was impressed. THEN.... The great wave of handset failures began. They ALL eventually failed. Understand that these were purchased new (not refurbs) for a LOT of money. Siemens replaced them all more than once, until the original warranty ran out. As soon as the original warranty ran out, it was suddenly not thier problem, even though they agreed that I had not had a functional handset more than a couple of months. Of course, then replacing the handset (one, apparently, doesn't repair these little gems) became prohibitively expensive. The base, as far as I can tell, always worked fine. It still does, I think, but since I have no handset to access it as it sits electronically blind and deaf, I can't really tell. In summary- the handset is the problem. Replaced the whole thing with a Panasonic system, which works perfectly. Do that instead

poor support from Siemens for this set as it is discontinued:
DO NOT buy a refurbished set. Mine lasted just past the 90 day return policy and stopped working. Siemens are not interested in fixing it.

Good system, but only lasts so long...:
We've had the Gigaset 2420 with 3 wireless units for almost 3 years now. The battery life on the wireless hand sets has been terrible all along, and we've even tried changing the batteries. Now, one of the wireless base stations has starting to die on us. The conversation begins fine, and barely lasts for 20 seconds or so. The quality of voice starts to stutter and gets really..really choppy. Finally to the extent that one has to drop the call. Although its out of warranty, but for the of this system, one would not expect such a poor quality from such an expensive set. Our much inexpensive phones from other manufacturers are still working flawlessly. I would NOT recommend this system to anyone.

Excellent Phone System:
No clue if the other reviewer's experiences are typical. In Europe Siemens phones are equated with high quality. It is possible the the US made units have quality issues. However, I own a base and 4 handsets I purchased in the US and I am constantly impressed with the performance and I like the nice design which never looks outdated. I have put in the new Duracell high capacity NiMh and my wife's unit indicated 2/3 FULL battery level after 6 hours (!) of talking while her friend already had to switch phones twice. With the new Duracells I expect the standby time to be stretched as well (I believe 300 hour normally). One thing I know is that you have a damage risk if dropped on the floor as their shape (long + straight) can cause display issues if it falls on a corner. So if you expect to drop it a lot, you may want to look futher (and this is the only reason to deduct a star).

Poor product with a nice look:
I've read some current reviews about this phone system and decided to add my review late in case anyone thinks about purchasing this discontinued system (refurb, ebay or where ever). Take heed in the negative reviews. I purchased the base unit plus 3 additional phones a few years back from Circuit City when it was still the top of the line. It worked great for 9 months, then like other reviews here, the system tanked without a single thing changing in our house. All of a sudden the sound quality fluctuated from serviceable to horrible, handsets could no longer lock onto the base unit even from the next room or feet away from the base unit. The answering system becomes frustrating over time because it seemed to have problems of it's own picking up, recorded message/greeting. Customer support was a bad experience, online support is nill. We still have the phone system sitting in a closet and I was looking for the manual, yet up to par with the rest of their support, you cannot find it on their support web site...I found it here on Amazon where I guess some kind soul submitted it and brought me to write this review. In France, Siemens phone systems are the rage my wife just returned from her trip...but it must be something with the Euro models. In the US, they are junk. Replaced the Siemens system with a Panasonic 5.8ghz KX-TG5100M system for about 2 years now and have had nothing but fantastic success. The only negative/problem we encountered was the system used the NiCd 850mAh batteries and a year ago during a week long power outage (hurricane) the $25 batteries drained and would not recharge no matter what. On a hunch, I called Panasonic customer support and explained my situation and they sent me new 1000mAh NiMH batteries for all my phones at no charge. To this day I have yet to experience 1 real problem. Panasonic makes great phones, better to spend your money on something other than Siemens
