This a good loader for a gun with a 13 ball rof. Thought I was outrunning it with my spyder, only to find the sound activation wasn't always agitating when I needed it to. I have to turn it off and on to get it to reset and work correctly when this happens. Both me and a friend of mine bought the tsa's at the same time and both the shells are broken after 6 times out. Batteries do seem to last forever. Have yet to replace them. More functions on the lcd model, but yet to use most of them. Shot counter not to accurate. Pretty loud also. Very annoying having it spin while just walking onto the field. Not to hot on the sound activation method.
Pretty solid unit for the money. Don't buy for a gun that shoots 14+ though. Think the revy would do the same job without all the bells and whistles for a little less. Get a egg if you can spend a little more.
