Personally I think the Tippmann 98 Response is awsome and if your like me and play with friends that have those high powered 1500 dollar guns then all you need to do is get this and you can shoot as fast as they do. I bought my response on ebay for 50.00 and so far its been very good to me. I did try to install it myself and put on a few pieces backwards so its pretty complicated, took me about 2 hours to figure out especially if you havent looked at the inside of your tippmann before ( I recomend letting a paintball shop do it! )
Very fast (8 balls a second about)
Easy to ajust how fast the balls shoot
Complicated to install (I would Recomend letting someone that knows what they are doing ex: paintball shops)
Freezes up the gun if shot to much
I have had a few problems with it and I have had it only for a week, but maybe its my gun.
Overall I give this 9/10
Great Product and very affordable
