Bests & Worsts Reviews from Amazon

Was really looking forward for this z creeper; however it was all disappointment. The caster nut does not fit due to bending of the frame done wrong and comes in the way of nut to fully attach to the caster. I tried many tried, switched casters, also made sure threads were there as the nuts would fit on casters by themselves without putting through the frame. Attaching picture to show how the wrong workman ship of bending of the frame is in the way of nut to attach to caster, circled in red arrow on the picture. The folks who complained about nuts with thread problems probably received the return product by someone who used elbow grease to try to tighten these which is not possible, or they themselves ended up doing it using power tools or excessive force. This is the main culprit for majority of the folks in reviews where their casters keep falling of. This is very simple problem to fix by manufacturer or someone who has full garage tools at shop to try fixing by self which I do think think want to do after wasting time on these casters. Also one of the seat edge has two cuts already so I plan to return these. This would be awesome creeper if it did not have caster issue. I doubt about the validity of reviews with 5 stars for this product.
