grey box thingy, worked well, but disappeared
Radarchron (works good, didn't disappear)
94 Autococker, 03 WGP hinge w/ dye sticky 3, hollowpoint 3 way, Palmer micro rock, clippard ram, sheridan inline reg, 16" smartparts all american, 32 degrees small drop
Made out of plastic, helps when washing off the paint so you can return it
The hole is smaller than paint
It is a shame that somebody would go to the trouble of designing, making, and selling something without ever using it to see if it works. It doesn't. The thing is actually smaller than the paint you are supposed to shoot through it. Attaching it to the barrel was more of a pain than it should have been, but I was willing to overlook that if it worked. Which it didn't. Luckily Walmart is very reasonable about returning things. I only write this review because the average score of 4.5 may be misleading some people into thinking that it must have some functionality, so I must work to discourage that notion. However, I guess there must be some out there that paint goes through, so if you are sure you can return it, I guess it couldn't hurt to try. Of course I don't know if it can measure speed if the paint doesn't break.
This is horrible, astoundingly, mind bendingly horrible, I mean, who makes a chrono that you have to shoot through, that is smaller than a paintball. Idiots, that's who.
