BalazsTU,
Several years ago, I used to order computer components from NewEgg.com and I always went through the reviews before I purchased a product. One thing that I noticed over-and-over was the following: even the Very Best products always had some negative reviewer who slammed the product. 99% of the time, the issue was NOT the product, but the reviewer. The reviewer was either bitter, uninformed, had improperly installed firmware, or was a newby who didn’t have enough background to know how to correctly use the product. After a while, I learned to ignore and skip over the negative reviews on extremely popular products. It’s a number’s game.
Did it ever occur to you, that IF all the other reviews here have been very positive, your interpretation or lack of knowledge may be the issue?
Also, I don’t see that you have you given the developer the chance to help you out.
