I had high hopes for this product. The idea of a keyboard that folds compact yet allows me to type at full speed on the blackberry sounded great. Unfortunately, the execution is not there. After spending several hours with this product, I finally concluded that it will not work on a blackberry 7130, which is the Verizon equivalent of the Blackberry 7100 from T-Mobile.To make matters worse, when I called the manufacturer for support, I repeatedly heard the greeting "your call can not be connected at this time". After a few hours, I got through to an auto attendant, and when I pressed zero for the operator, I was offered the opportunity to leave a message in the generic mailbox.The only support option this company offers is via email, so I emailed them with my configuration and the error message I was receiving. After 3 days I still have not received a response. Furthermore, their web site has only very basic information on the product, and offers virtually no troubleshooting support.Finally, I assumed that the reviewer below who commented on the comma key and period key being swapped must have received a unit from a bad batch, which surely would be corrected by the time I received my unit. Wrong! My unit had the same two keys reversed too.How can a company operate like this? They should be embarassed, and you should avoid this product at all cost. There are other bluetooth keyboards out there from more reputable manufacturers that have more pride in their operations.For what it's worth, the unit did work on a blackberry 7100 from T-Mobile. Unfortunately, I bought it for myself, so it didn't do me much good.
