First off, the first video techpb did wasn't a review, it was an unboxing. Correct me if I'm wrong, but it's kind of difficult to give an honest review when you've only just unwrapped the thing. The second video they did WAS a review, and they were very honest with it. They did mention the problems that the first gen had, and they did say from their own experience that it was fixed. It wasn't a poor review, it was an unboxing video and their first impressions. If you want poor reviews, head to pbreview. You'll get everybody saying they love their gun, nomatter what it is, even if they haven't even used it.
Secondly, the second review wasn't a year later, it was just under seven months. Mike has always maintained that he won't give a proper review until he's gone out with the marker and beaten the hell out of it on the field. Given the fact that the sent the first gun off internationally to be fixed, and then got one of the second gen guns, that seems like a fair time to build a decent review of a gun.
Now, I get that you've had a bad experience with one. That's fine and you're entitled to your opinion. What you have to remember, though, is that the Invert Mini had awful problems in their first few generations, and then quickly became a popular marker that still competes today. Considering it's age, that's an acheivement.
Oh, and Mike isn't a 'dope'. I've never found his video's to be unfair and he does a lot to generate new interest in paintball. You can hardly criticise that.
