GLACIALStress Relief Desktop Punching Bag I Comes with Desk Clamp and Extra Strong Suction Cup

This product is sturdy, and is great for stress relief! We use the grip rather than the suction copy and haven't had any issues with it coming loose or anything. When the air gets a little low, it's super easy to use to pump to fill it back up!

I bought this for a gift for a coworker and I bought myself one to keep on the desk on those days. I just have fun or need stress relief. My coworkers have been using it also.

This has been a fantastic outlet for my ADHD kid. For our purposes, it needed to be clamped onto a hard-fixed surface (in our case, the corner of the kitchen counter) so it wouldn’t wobble furniture around when it gets smacked hard. It lasted under heavy use for 4 months. It worked its way off the counter today, and then when I over-tightened the clamp to put it back, the metal clamp cracked. I wish the clamp metal was stronger, but I’m going to order another one anyway because this thing has been great for my kid, and now I know not to overtighten the clamp. I can’t imagine how you could use it for any length of time with the suction cup, but we didn’t try, so read other reviews for info on that.

I purchased this for my employees, opened it at work and it is missing instructions and a needle to pump up the ball. Kind of useless without being able to pump it up. I think I have a pump at home that I’ll have to use. Hopefully it works.

I cannot stress enough how there is literally no way to set up this product. The suction completely does not work at all, and the piece you’re supposed to be able to use to screw it onto something with the clamp just does not have the pieces to even allow you to clamp it onto anything. Do not buy this product unless you have your own tools/ways to mount it to something, because the tools it come with do not give you anything at all to work with. I wish there were a way to emphasize more effectively how absolutely useless the tools provided are.

Very good product, the clamp is sturdy and the bag not deflate as easyly as other similar products, also, the spring is stronger than the most other desktop punching bag and the bag's PU is better. You can punch it hard and the bag will not crash against the table/desktop.In general I'm very satisfied with this product, however the suction cup is not strong enough to support well the spring but the clamp is outstanding.Beware when you strike this bag the vibration is very strong so the table where is clamped will trebble much, so a sturdy table is advised.Highly recommended

For the low price this is worth getting. Some have commented that the suction gives up soon. That is true, but you just have to press the suction plate down now and then when you see it ready to get loose. Another problem someone mentioned was that the ball got unscrewed when used. True, but can be prevented by well tightening the hex washer on the base of the ball before threading in the spring base. You would need an open end wrench of the correct size. If you cannot get one of these the problem stays; maybe ask if someone you know has such a wrench. In any case, if the ball starts to unscrew off the spring base, then turn it back.ADDED: Yes, elastic base needs pressing down every 30 seconds. But there is more. I wanted to switch to clamping to table edge. But! I can't turn spring base out of rubber base. It got turned in so tight it won't budge, especially because elastic base turns as column us turned (with pliers through cardboard padding so as not to damage thread. No luck. Only thing to do is file spring column to get flat area for using pliers, but if thinner in a place the column might break during boxing. SO: best thing is to leave it as is.
