Question: How fast does this machine pitch.
Document: My grandson mastered the Pop A Pitch at 3-1/2 years old. Easy enough to keep him focused for thirty minutes.
Works great. Make sure you read instructions. If you do it will work as intended. My six year old enjoys playing with it for fun. And it's something he can do on his own when we can't pitch to him  My daughter gets more out of it. I would say good for age 3-5 but if your son/daughter is more into real baseball early on then I would just throw a ball to them.
this is a present for our 6 yr. old grandson, haven't been able to  give it to  him yet but am sure he will love it, he loves being outside doing all kinds of fun things.
bought for 5 yr old birthday that is starting out in T-ball. He loves it and his age  has the coordination to do it all himself.Its now 3 mos later and the product is still going strong. Curious to  see how an entire summer holds up.
Works great. Fun game yo play when my son hits and I field. No batteries. Yeah!
Works beautifully and the grands love it and so do their parents! This toys is spring loaded and requiers no batteries. Love it!
When my nephew opened it, everyone fought over playing with it (including his 5-and-a-half year old sister and 18-month old brother). Fortunately my nephew shared and I even got in on the action - it was REALLY fun!!! !We put it together in 5 minutes or less and there are no batteries that I saw. You simply step on the pedal and in a second or two, the ball pops up.
We lOoked in several local stores before buying this on Amazon. I think it's a great easy toy for practicing hand eye coordination.
This thing is a HUGE hit for ALL ages! !I bought it for my nephew who is 3-and-a-half and loves baseball. Before I wrapped it, I showed it to my 23-year old brother and he asked if he could try it (no!). While I was wrapping it, I showed it to my 28-year old fiance and he asked if he could try it (no!
This helps with hand-eye coordination and gives them the confidence they need to hit the ball. I think this is essential to young ball players!
