Question: Can you use it in the basement.?  It looks  like it requires outside because it requires steaks to go in the ground?
Document: Great swing trainer, easy and quick set up and take down. Can use outside, in garage or basement anytime great product!!! !
Bought it for my 9 year old and two 7 year olds. My kids really enjoy it and so do the adults that come over. I've seen steady improvement with all of my kids.Built very sturdy and looks like it will last a while. I did go to autozone and buy some grease for it (doesn't come included and is necessary). If you do order it you may want to also order some grease for it as well.
Very well built---I'm impressed by the quality of this product. Looks like it will last a long time. Bungees will need to be replaced, but they are not expensive.Comes with a tote bag. Fairly easy to disassemble and carry to a game or practice field. However, the rotating pipe is greased and will make a mess unless you put it into a separate bag of some type.It is really sturdy if staked into the ground.
This batting trainer works great - it's of good quality, looks great, works as advertised. I like the fact that on a rainy day, my two boys can set it up in the garage and still get in a few swings. They are 7 and 10 years old, so I use only a single elastic, which they can strike and have it spin all the way around. They like to use it.
I probably use it more than my son, to get in some BP for softball season.It has definitely helped both of us - him with power and me with accuracy. It forces you to swing through the ball to get a nice smooth return of the target on the arm. I like to hit it on the return, which requires more focus and a quick bat. I am planning to start bringing it to practices for my 11U team, even though it's heavy. Breakdown/setup is pretty quick.
This item was an awesome tool for my 11 year old son. He would use it 3 to 4  times a week and it helped him make better contact throughout the season. Very easy to assemble and I keep it in my basement so my son can use it all year around.
Product is excellent. Two boys aged 11 and 14 were wailing on it with no issues. I did not use the ground stakes, they just set it up on the driveway and had no issues. Nice to be able to modify the resistance as we started with just a few bands and worked them up to 4. The one negative is that the carrying bag it came in is terrible. It is tissue thin and ripped at the handle the very first time we picked it up.
I tell other parents and coaches aout the hurricane but none of them listen. This is your chance to won a secret weapon for feeling good at the ball field when your kids go from batting last to lead off or fourth hole as mine have. By the way, we have ours in the garage to avoid the annoying Texas rain and have never needed to use the stakes or even weights which would work fine if we did. It does not slide much if at all on our garage floor.
His swing has definitely improved over the winter months. When not in use in the garage, we just slide it over to the side and back the car back in. For our purpose, it stays out of the way pretty well until needed.One last note. Letting the bat go is an ongoing &#34;worry&#34;. I realize that one loose bat will be a game changer for practicing in the garage, but we invested in batting gloves for this reason alone.
My three boys ages 8, and 6 all play baseball. We bought this to help them with batting. We have had it about a week now and they use it everyday. I can send them outside to practice by their selves which is great!!! They have already showed some improvements in batting and the best thing is that they can use it from age 5 till they are grown.. I would recommend this to anybody.
