So was on pbreview reading up on the invert mini when i came across this...
" I bought this marker as a gift for my son in March. We owned it for about a week before we decided to take it back to the paintball store we bought it from. I see from the recent reviews that other people had better luck than I did. I hope I just received a "lemon".
I bought this from our local paintball store as a gift for my son. When we got it back home I checked it out better. I am impressed with the locking case it comes in. I like the price. I read the manual. It was pretty cut and dry, easy to understand and adjust settings. I was really impressed when we turned the eyes off and dry fired it, we then tried the different modes. Very nice.
This was when it all went bad. We put air and a Pulse loader to it. It did air up no problems. I put old paint in it and it chopped. I did not even get 10 balls shot thru it. No problem, it was probably the old paint. Bought a fresh case,no dimples etc...Chop, chop, chop. I tried it slowly it still chopped.
When buying this at the paintball store I ran into a guy who had said that I would have to turn up the bip as it is set super low from the factory. When resetting the board he said to raise the bip up alot because it is wrong from the factory. So, I tried that. It did not work. The very next day after buying it I had to take it back to be fixed from the paintball store where I bought it from.
I received it back a few days later and they said they talked to a tech and he walked them thru the problem. It was a setting of the dwell. When resetting the board the setting for dwell is 38, my board only resets to 28. So instead of replacing a defective board they just set it up to 38 manually. Keep in mind the dwell on this mini is adjustable from 1-40 and default setting is 38. So, you can only adjust one way really. From what I remember from the manual, the bip was the same way,adjustable from 1-40 and it's default had it set real low like 8 or something.I had also found out that I had the newer version 1.2 of the board so it was revised already. So then they shot 2 hoppers of paint thru it and said it was good.
My son went to the field the next day and of course it would not shoot, just chop, chop, chop. So I went into the board and made sure the settings were exactly as the manual says its supposed to be and tried shooting paint thru 1 ball at a time. I also turned the reg pressure down all the way the slow the bolt down. As I looked at it, it looked as if the ball would hit the detents and go up and try to feed back to the hopper. Exactly what it was doing. Back feeding into the hopper. At that point I tried taking the detents out to see if the spring tension was adjustable which it is not. so I cleaned them, and put them back together. Then I took the mini back to the store and demanded my money back. They finally let me exchange it for a different marker. They said they probably would not be selling anymore Minis because they don't want to lose all of their customers.
Since that whole experience, I have no big problems with the mini, it seems like a nice marker until you shoot paint thru it. If it wasn't for poor quality control, this review would be flip-flopped right now. But because my mini did not shoot even 1 ball at a time I gave gave this a 1. I also took into account that the default settings on the board were totally messed up straight from the factory. Also that customer service would not replace a defective board."
