I write reviews really seldom, but this time it looks like the guysdeserve some appraisal. I purchasedHiBoostF10-GSM as a gift for my Papa who lived in the countryside. Before he could only talk on the phone on his front porch. Now the reception is greatinside. What surprised me even more how their support work. I talked to manager Jane most of the time. She answered all my questions, advised best model, sent me about about dozen of e-mails so that I could have everything we were talking about at hand and even called me when there was one-day delivery delay. 5-star service. Great company, great buy!
