I have always wanted a speed bag, despite not knowing anything about boxing. Since I live in apartments and tend to move quite a bit, I did not feel like buying a professional one that required making holes in the wall. When I saw this I bought it right away, as I have a chest-high counter that seemed to be made specifically for this. It seems to work pretty well, but the suction is not very good. Once I managed to smash a dish when the thing simply took off after a punch, but that was a rare event. What happens on a regular basis is that the thing moves while you use it. However, I could have received one with a defective suction cap, so do not be discouraged. If you avoid putting breakable objects on the other side of the speed bag, you should do fine. Even if it takes off, it is not heavy and thus it is unlilkely to do much damage. Would buy it again despite this defect... 4 stars

We purchased this desktop punching bag for a Technology Department office. We put it on a table by the door so Techs can punch it when they come in or go out - to relieve stress. Amazingly it lifts up everyone in the room when someone punches the bag because we all understand the pressure and frustration that the work place produces and now we have a fun venting mechanism.

I was afraid that the suction cup bottom would not hold the bag in place - but the cup securly holds the bag on the table top even with excessive and forceful punches.

When and "if" this one wears out - we will definitely order another one. No office should be without one! 4 stars

I purchaced this product when I was looking for a speed bag that would be easy to install without having to put holes in my room. It is very fun and easy to use but the suction cup doesn't want to stay attached. Despite the tackyness of it, I have resorted to duck taping the suction onto the table and have had no problems since. Once again, proof that duck tape should be the #1 sold item on Amazon. 3 stars

Great way to get rid of stress in the office. Suction cup bottom works extremely well. 5 stars

I love this thing. It was easy to assemble, everything just screws on and it even comes with a little needle pump! Mine doesnt stay very well after you stop punching it or break the rythm. If you stick to the same rythm it doesnt pop off. The suction cup holds very well but the back and forth motion causes one side to creep up slightly, and it therefore loses its suction. I'd by it again in a second, despite this. Would probably hold together if i put some tape around it like someone else suggested, but its not really a big problem for me. People come to my desk and love it. Greatest office accessory evAr! 4 stars
