JMHO here, but Dobeck in the past has been a very good forum partner. There have never been problems with the original TFI, Gen 3 or 3.5. I think where they got a bad rap here was in introducing the Gen 4 a little too soon. It did have many problems. They tried to rectify those problems as quickly as they could but it left a few here with a bad feeling for their products which is unfortunate. They are a solid company and have some great products and I would welcome them back to participate in the forum once again. BTW I was one of the very first to use a Gen4 and it did have problems. I am still running the Gen4 and it has been flawless for quite a while.
