I purchased the BT Graphite twin 1100 one month ago. I made three mistakes: Ignored negative feedback.Purchased because they appeared good looking and good value for money. Ripped the packaging up before realizing just how awful the quality is.The problems are: Dreadful sound quality both on the receiving end and also for the caller. An unpredictable screeching noise that kicks in randomly forcing you to hang up. Poor, tacky build quality. I hasten to add I didn't buy them from Amazon, I found a really good deal from Littlewoods with discount vouchers. The deal was so good the phones are now enjoying a new life at the local dump.Save your money buy an alternative brand.
