At first I was like almost all here very excited because of the outwardly beautiful and solid quality. However, man must be extremely careful as this vortex is intended only for very light punching bags. Have the punching bag just the first 10 min. Train, when suddenly the bag lay at my feet. Thank God nothing happened. The connection between the wall bracket and the vortex itself consists of 2 washers made of very thin sheet metal, the upper of which is bent and slipped through the hole of the wall mount. I had hanging a 50kg bag on it, and as I said the first time I trained. Maybe it's just a processing error with me, because I have already read some reviews here but the statements the same, the holder should be intended only for very light bulbs or sacks. Basically not a bad product, but must simply state that it is by no means this is a mount for heavy punching bags. Aufgrunf the lack of information on the product and the associated risks, I can not be only one star and be glad about 4 fantastically unnecessary holes in the ceiling.
