Good product, but needs improvement 
I bought this phone about a month ago. So far it has been working flawlessly. That being said, there are a few shortcomings that I feel could have been remedied easily.
1. The speaker phone is not powerful enough and therefore almost useless
2. The graphics could have been better. They are functional but not attractive
3. The sound (earpiece, not speaker) is clear but not loud enough.
Overall, pretty convenient and certainly worth buying if you can get it for under $100.
Works Good 
This is a neat product, it was easy to set up and quite easy to use. Callers say the sound is very clear though on my end it is a bit “tinny” sounding.
The battery life is excellent and I can walk around the house and even outside and still use it.
I would recommend this to anyone except the fussiest people who would settle for nothing but the absolute best there is.
Linksys CIT400 
This phone is WONDERFUL!!! It has tons of features that regular phones just don’t have, a variety of ringtones, is extremely simple to use, and the call quality is excellent. Plus, it’s paying for itself with what it’s allowing me to save compared to regular landline service. I would recommend this phone to anyone!
Was tempted to give 5 stars
I purchased this phone a month ago. I am not going to give the things I like about it because it would be a repeat of all the raves in the 4 and 5 star reviews here. I just learned today how to get it to send my Skypein number to the people I called for their caller id (I was under the impression that Skype caller id wasn’t available in the USA). I have used the handset in my camper. That sends the signal though 3 walls of the house and the aluminum camper. I used it while I was in the garden today. Thats 1 wall and 150 feet away from the base. When I ordered the phone I was switching to cable from dsl and I had a lot of modem problems. The phone voicemail worked great when the system was down. I turned off my home phone yesterday and will save about 600 bucks this year (my cell phones are for backup).
I had one problem with the phone. Once it locked in restart (not sure if it was phone or router). I unplugged the unit connected to the router and plugged it back in. No more problems. I would like for the phone to be larger and heavier (more like a regular phone). I would also like to find another handset. I would buy this phone again in a heartbeat. I highly recommend it.
Nice Skype phone!
Works grrrreat! It feels a little light-weight and cheap, but I haven’t had any problems with it. Sounds just like a normal phone when I “Skype-out” to landlines. It would be nice to be able to add another CIT400 handset, but it’s looking like Linksys is not going to be making this phone anymore.
