    "They misspelled NOT Lipo ready
    it worked beautifully until my 7.4vl battery over heated the wedge connector and basically melted everything that was near it that was plastic. it WAS good. but i guess we are talking about the finishing product... which is broken...

    "Hidden Gem!!

    I dont usually do reviews but had to comment on this gearbox.

    At first I was a bit worried when the gearboxes arrived (I bought 4) in a plain brown box with no protection whatsoever! Like a couple other people have stated, the trigger assembly is wonky. I had to replace 3 of the 4, but aside from that minor issue this gearbox is Rock Solid. Mine had an Element Ball Bearing Spring Guide, and an Element Piston and Ball Bearing Piston Head. the gearbox is reinforced, and seals very well. Chrono put the gearbox at 375 FPS with a .25g BB so I think mine arrive with 120 springs instead of the 100 listed.

    Cons - Flakey Trigger
