Question: i just received the machine and the first issue is how to get the balls to feed. i puchased 2 dz orange balls and  not shimmying down. Can the rubber stopper be adjusted?
Document: Just assembled and fired up this machine for the first time and am very, very pleased. I have not found the issues of inconsistent location to be a problem thus far. Granted its the first time of the first day. From what I can tell, the issue might be caused by feeding the balls too fast. This machine is powered by one enclosed wheel and its not large. But that's a good thing over all. It folds up and will store nicely.
i am pleased with the machine,  i think it is a bit pricey for the quality, would like to see it configured a bit different. it works best if you let the auto feeder feed the balls if you attempt feed them manually you have to make sure you wait enough time to allow wheel to regain its set speed.
Can only use the balls they suggest, soft strike. Had to turn all the way to high to get to throw 46ft . This was for my son 1st year with a pitching machine. I went out and purchased a 650.00 machine and have no problems, throwing softballs, leather, soft, practice well worth it in the long run. Just invest the money up front you will be disappointed.
This is where the ball feeder comes in nicely. The way the feeder works is it uses the vibration of the power in the machine to shimmy the ball down. The time it takes to do this just so happens to coincide with the time it takes the wheel to get back up to speed. So it really is a good idea to get both. If not, you just have to wait about 5 seconds between pitches.
This pitching machine is not worth your money. It worked for one baseball season, it doesn't have enough power to pitch the balls. Save your money don't buy this.
With three boys who have played baseball this is the fifth pitching machine I have bought. Coaching kids and throwing to them over the years has left me with arm problems and I need a reliable machine. This machine throws light baseballs that look and spin like the real thing without the risers that make most machine pitch unrealistic. It is accurate and can be used indoors. It can be adusted for slow curves and aliders that break like the real thing. It is adjustable and accurate.
Those cost over $1,000 and you would need something like that if you had 15 kids taking swings and a time limit. But if its just you and a few kids, you really can be confident picking this one up in my opinion. See videos below of it in action.
I bought this for my 8 year old and it is not bad for the price but the accuarcy is not the best.
I bought this for my 12 year old grandson for his birthday this year. He loves it, but my husband and son-in-law said it was a pain to put together! But in the end it works well and my grandson loves it!
For older college kids it would be good if it could throw at bit faster but it is fine for batting practice. So far, I have found it to be the best product for the money out there.
