well i finally got mine a few days ago and i must say for the price i cant complain.since then i gave them to my brother and i upgraded to ic-3"s and they are great .we dont run them (the cars) until the batts die, but i can really tell a difference inthe power between the ic-3"s and RS batts. overall if your on a buget and need batts, for 24.99 i would say go for it.
