I have been a LONG time supporter of Flex (many many years) and I have had just about every radio they made. I recently had a problem with a warranty transfer with a good friend of mine. I'll keep this short... I was in the market for a new 6600M and my good friend received his last week and he decided not to keep it (for his own reasons). I took the opportunity to take it off his hands and in doing so saved Flex the cost and trouble of taking it back under their 30 day satisfaction guarantee. I gave him the money he paid for it and made it mine. So, I'm very happy with it, love the radio (as if I was not going to) so my friend started to communicate with Flex to get the transfer of the warranty completed. So you would think this transfer would be free seeing it was SO new (only a week old) or at a substantially reduced rate (As I do understand paperwork is not free). Keeping in mind I myself saved Flex the cost of taking this radio back and not being able to sell it as new as well not to mention my friend is also going to purchase a new 6400 from Flex. In spite of all this, they charged him the standard $90 to transfer the warranty to my name. Now some may think this is okay and it may not bother them. However, with Flex knowing who it was going to (me) and how much I have spent on radios along with my friend showing interest in purchasing another radio (6400) from them this cost would be waived. This is not good business or customer appreciation. I'm stating this because he's a good friend of mine and with all the details surrounding this, this was not the correct thing to do.
