Question: Can the stakes be inserted into a baseball field or just in grass?
Document: Along with gloves, balls, bats, and helmet, this is an absolute must for any baseball/softball player. Just watch that you don't saturate the sporting field with pitchers because this may make those using this slightly addicted to the art of the pitch.
When throwing at full speed the pitching trainer does not move at all (with 2 stakes clumsily put in). Because this unit is overall wide, has a good weight, and is very high--it will not move regardless of how fast you throw. It does not matter the kind of pitching you are doing, this pitching trainer will catch everything.
I suspect they will come in handy when we put it on the grass. If your child likes to practice their pitching, this is a great tool and will provide lots of fun!
Set up was super easy...did it all by myself. Love that it came with a storage bag. My 7 and 5 year old couldn't quite throw the ball hard enough to get it to 'return' but I imagine that will change as they get older and stronger. The stakes that came with it are pretty much useless and so I had to fashion my own. Other than that, we have loved using this.
The poles snap together with tension between the side poles and the net keeping the unit upright and tight. Because it is so easy to assemble and transport, we've set it up at home plate at our local ball field so that he can imagine himself in the rotation.Nothing substitutes for the big league experience, but the Quickster Pitch Return gets your young player in the game.
This was very easy to set up and install. Even though the dimensions are clearly 7' x 7' - it's still kind of hard to believe how big this is. The tension is just right and returns the balls back very well. It has a good strike zone - and the reversible batter for purposes of pitching to a R or L hand hitter is great. The included ground stakes make it even sturdier.
The pitching rebounder is big after setting up. So big and it's hard for any pitcher to miss the net. Though it's big, it's very easy to put up and take down, no tools needed. It comes with stakes for securing it into the ground. The net itself is high quality and the thread is pretty thick. Personally, I feel this net can last for a long time.One of the key features is that the net perfectly returns balls back to pitcher.
Total setup time is under two minutes if you've done it before. The net can go on backwards if you want an image of a left-handed pitcher (the picture is basically painted onto the netting).The large net is great because even if you miss the strike zone, the ball will likely still hit the net and roll back. We start with several balls and it's quite a while before we have to go fetch any. The four included U-stakes effectively hold the frame in place.
Because of this you get something you might not have expected, as mentioned briefly above: You can realistically set this unit anywhere--even in the confines of a closely built together neighborhood without the worry of the ball bouncing and hitting, say, a nicely clear window. [---The Size---] 10/10Know when you buy products in the sporting field that have different sizes and shapes determined by their classification e.g. Youth Basketballs, Highschool Bats, Youth League Baseballs?
My husband is not an aspiring baseball player, but enjoys hitting and pitching for fun. He has a batting cage for the former and I thought this would be a nice addition.
Answer: yes
