We recently moved into a house where we were struggling to get a single bar of reception, it was impossible to make a call and struggled to send texts, so we were keen to find some kind of solution. Having tried cheaper products in the past we were apprehensive about this but were willing to give it a shot and bought the "MR GSM 900 PRO". We now have full reception all round the house and it couldn't be working better.
If your looking for a solution to improve mobile phone reception, don't waste your time with cheap products that you stick on the back of your phone and don't work, a mobile repeater is definitely the way to go.
Thanks very much to Mobile Repeater for their excellent customer support.
