are these similar to the Orange brand?

are they reliable?
I have two of those... now. I got the first one from GorillaBobs. It didn't work, could never get the fast flash to bind. So he sent me another one which did work.
The one that didn't work was a bit interesting. The solder job on it looked a bit 'off'. I'm an ET so I blasted the entire board with my reflow station (was sure I got it too hot

) and it started working. Of course I have zero confidence in that one now. LOL
The good one... can't really speak to that yet. It's on a slow stick that I haven't maidened yet. Hopefully this weekend. /crossesfingers
Edit: Just to note, RCG has a large thread on the lemons. The manufacturer was replying at one point (haven't checked it out in a while) and seemed quite responsive to suggestions from customers. It's the reason I decided to try one to begin with.
Edit Edit: And no, they're not clones of the oranges. I have an orange and now two lemons, the boards are different.
