Question: Which is it?  Powered by 4D batteries and/or a plug in, or plug in only?  This is major.  I don't want my marine battery and converter getting hit.
Document: I have three young boys who play baseball and I can say I was as about as much impressed as they were. It was a great idea in theory, but having to plug it up was a bummer and I don't want to waste batteries with the outdoors. In theory the balls drop right down into the "shoot" but they don't without assistance. It only shoots about 3 feet up in the air.
It's nice that you can take it to practices, but without an outlet, don't plan on using it very long or bring extra batteries. It is a great concept but is slightly underpowered. If you want to help your child hit better,pass on this and getSKLZ QuickSwing PX4 Baseball Trainer.
I wish it threw a little further. Max with spring cranked all the way is about 4'. Unless on a perfectly level ground, the ball feeder doesnt work correctly (wont self feed).I use this mostly because I was sick of getting hit in the face with foul balls when doing soft toss to my 6 yr. old.
My little boys are beginning to play baseball, and this product has really been helpful in training. They are able to hit and catch off of this machine. It isn't as fast as a pitching machine, but it is not slow either. It throws a consistent pitch. It takes some of the pressure off of me as a parent to deliver a perfect pitch. It is easy to set up and load, and I like the ability to use it plugged in or with batteries.
Awesome product!!! My 6 yr old son started showing major improvements in his batting skills after only the second time. We use tennis balls to practice catching pop flies and saw a major improvement in that area as well!! I will highly recommend this product to anyone. The only bad thing is that it's plastic so balls will hit it and break the casing, I solved this issue by placing a concrete block in front of it to protect the unit.
My son is 5, and this ball trainer works perfectly for him...right now. As many other reviewers have mention, the toss is pretty weak, but for a young child just learning to hit, it works. If your child is a skilled player though, you're definitely going to want to look around for something with a little more power.The machine has an overall 'flimsy' feel to it, and I doubt it's going to last very long.
Maybe we just got a defective one, but with all the other bad reviews I have to think this product is just junk.Keep shopping - this isn't the machine you want to spend your money on!
It's just as well; they complained that it didn't work, so they left for other things to play with.I guess this just goes to show that you can't get a $1000 pitching machine for $60. I knew that going in, but I didn't know that was getting something that wasn't even worth $30.
But with the device's feet adjusted for minimum height, it still flings them too high for my kids, so I had to put some rocks under the back end of it. (A thick board would work better, but I haven't gotten around to trying yet).However, I think this device has a major safety issue. It uses a pretty modestly sized spring, which is connected to a lever with a plastic cup-shaped section to hold the balls.
The SKLZ catapult is a great tool for helping kids improve their batting skills, particularly if they are like my son and have a dad who can't consistently pitch hitable balls to them. In just a few sessions with this device, I can already see an improvement in my son's batting skills and confidence.Other pros: The device is very lightweight, even with the 4 D batteries.
