I own both the Losi and the Pro-Line fuel gun. The Pro-Line is 10 times the quality of the Losi, and is faster IMO. My Losi leaks a little too, & I've done several things to it to keep it from leaking as bad, but still drips alittle when full. I do like the way I can fill the gun better with the Losi, but that's about it between the two.
Between the Losi and the Pro-Line, I would pay the extra cost and get the quality gun. If you want a Losi, I'll sell you mine for $25.00 shiped...
