Worked well for me. I run on 2s w/ tenshock 4400kv motor on normal 10th scale tires and its been 4 months. Diff is still on the original build and still filled with 100k fluid. Hasn't blown up on me or had and premature wear and tear. Just make sure your motor mount bearing is turning freely and you shouldn't have any problems.

I think it was the right one but within a day of driving (5+packs) it broke again. I think it is because i had 1/8th scale tires.
