So I have to say for the price I was a good but not great Delivered delivered products only as wurde..dazu later. As I read in the other reviews are the collars after only a short time to solve ..Leute Seriously what do you expect ?! This shows that the majority of the buyers of this product have no idea what they have there actually bought such point that the collars come off is because the is bar a coarse thread so it comes to rapid wear of the thread that happens one to thus if you schrabbt with the weights over the thread thus you take stuff off the same happens with the disk thus formed in the disc in the core hole more game (until the event occurs but it takes a very long time) is this not to prevent and ever more play the hole has the more it wobbles on the rod and the weight naturally shifts to the collar of sometime MINIMAL yields the result jiggle the weights or turn sich.So whether top bar at a high price or low at some point it happens at all .I had an account in three gyms and none where I was vorfand device as there are a few people here like trained hätten.Wer at home here makes little bad buy it is worth because the bar is top in his hand and it makes enjoy it to trainieren.So now for delivery: Top Monday ordered Wednesday since early! Top Shipping but unfortunately it came with the package GLS looked totally eaten and yes I guess this leads also to small defects katschen small but not too bad, the bar keeps eh not for eternity like almost everything;) So top part can only recommend much fun training Gruss Andy
