Question: what does it run off of? Battery or Electric
Document: This is a great product for the money. Looking forward to several seasons of use! May have to use pitchign machine balls instead of real balls, seems to try an dremove the cover of the balls.
The readouts are not always correct. I have found that 5 1/2 is the setting to get around the 38 MPH. I do adjust the speed up and down, because other teams have their speeds a little faster, and this machine does a great job at slow and fast settings.
So far so good. Haven't been able to use as much as expected but the use I have had worked ell. Both for a pitching machine and for fly ball practice. As I begin using more ill update this review. For the price ... A quality machine.
Price is good and we have used it for 2 months now problem free. It does pitch a little faster then expected.
If you clean the wheel and pinch bar after you use it, black marks probably will never be seen.I have yet to figure out a simple way to make a batting cage (price some nets) so at home I use a pitch back net in case my boy misses the ball. He has so much fun with this machine I feel this was probably one of my best purchases ever.
If only there was a "teach the kids to throw a ball" machine.During games we use the regular Babe Ruth baseballs, the hard leather ones. I have NEVER seen a cover come off a real baseball with this machine, EVER. I have seen a cover come off of one of those cheap spongy balls, but I can pull the plastic off with my hands and this is after all a "pinch" machine.
I use the rubber balls at batting practice even though they bounce a lot, but I can use them for at least 5+ years. The Bulldog machine spits the balls out evenly and consistently when you learn to feed them the same way. Yesterday, on a team of 15, I let our kids hit 19 hits with the rubber balls and the last hit with 3 strikes of real baseballs.
I took a chance with this Buldog machine and it paid off. Compared to the $1200 Atec machine I've used prior to this, I feel the Bulldog works better. The Atec's wheel strips off the cover of 12" Softballs (Leather or Synthetic) and throws off the balance off the machine, this hasn't happened with the Bulldog.
I love it it is perfect for little league play very accurecte also great deal on it also duy it
I have never set it up with softballs, but our town bought one more machine for our girls 6-8 year olds and I was told they love the machine also. No wild pitches coming at kids, the ball in the same place every time.
