these orange Gel ones good? i have bought from that ebay seller before and always been ok. Of course i am still trying to get the dealer to replace it for Free. they want me to bring it in this weekend.if you want ASAP, your local walmart prob. has a replacement, you might be able to look it up on their website.
I have a link saved, member JSP said he got one here and was happy with it, could msg him to see if still holding up as it's been cpl years
