Nokia 1661 (black, T-Mobile, - Prepaid)

Pros: Small and lightweight...a nice change. Very Inexpensive. Not a bad looking phone.

Cons: Apparently it sacrifices a lot for the weight. Flush buttons are hard to accurately push. The plastic screen scratches easily. Would only purchase this again as an emergency phone.

Summary: Cons certainly outweigh the pros on this phone, so it was no wonder that this one made CNet's list of loathsome phones. As a basic phone, this does the job but don't expect anything more.
The buttons are the worst feature of this phone. They are very hard to accurately press...just the worst design I have seen. I had thought the protective film on the screen was for product shipping, so I promptly removed it. Bad mistake. Scratches appeared immediately after carrying it around in my pocket. Call quality wasn't as bad as stated in the article. Calls came in clearly and others could hear me well enough.
Within two months of owning this phone, it started asking for a security code after turning it on. The default code wouldn't work, and customer service only offered to replace it. Some web searching turned up that this was a common problem with this phone. The phone was rendered useless, but I was able to transfer the SIM card to a different one and save the leftover minutes.
Do yourself a favor and spend a few more dollars for a better quality phone.
