Yes, yes, I know I am not a kid. I'm a dad.
My son was having trouble with getting his velocity up in his pitching. He had fine movement and location on his pitches. The term "mph" is what he loves to know about. So I bought this as a motavation tool.
At first, he was throwing 52-56 mph, topping out at 58. After putting the gun on him, he didn't like the results. I said "OK, then, let's work to get it up to 63". He did, and beyond that. Soon 63-65. Then 67-70. Now he's throwing 70-73 at age 13. Also, he began working on a changeup a little while ago and he's got it down to a 10-12 mph difference according to this gun.
This is an affordable gun, while it seems a little slow about 2-3 mph(we went to a Giants game a few years ago and threw 68 on an expensive gun), it still works. Also, to all you who say that using a gun on a young player is bad, it is not if you stress strikes and mechanics and not overthrowing.
Hoever, I highly recomend this gun to LL coaches and pony League coaches. 4 stars

Durable. Tracks mph and gives you a reading of top speed. Seems to be accurate. Reads the same mph as my zooka pitching machine.

Takes 2 c batteries and they are still going strong after a month (probably over 500 readings).

Great for kids and adults. Reads speed of ball coming toward you or away from you so you can use this with 1 person or 2.

Recently brought this to a pool party and the adults had more fun with it than the kids. 5 stars

I am extremely satisfied with this product. It was recommended that I get a significantly more expensive device than this one for the purpose I wanted to use it for. I saved myself a great deal of expense as the product works perfectly for the function that I purchased it for. This device is extremely compact, but has a large highly visiable screen. 5 stars

I am 100% happy with my Bushnell radar gun. I mainly bought it for use in motor sports, four wheeler racing, motorcycles, and various activities involving speed. It uses K band so that is a big improvement from X band. The range on this thing is totally unreal, I can catch someones speed from over a 1/4 mile away, pretty amazing. Bottom line, for this price it is an unbeatable buy compared to the $900 stalker guns. I love this thing!!

It got to me and upon my sons birthday and opening it (a month or so later) it worked for about an hour and since has not registered speed correctly. A huge disappointment and waste of my money. 1 star
