So far, 5 race days with no issues. I like the lighter weight, and the slightly smaller physical size in my Tekno RC8. Excellent power. Excellent price. I bought these after puffing two Gens Ace packs in one race day. If these last a season, I'll just buy fresh ones every spring. Thanks Amain! EDIT: Have a few more race days on these, and they're still working great. Still no issues. I am very surprised given the price.
