Bests & Worsts Reviews from Amazon

I am changing what used to be a 5-star review. Having read what others have said about the issues they experienced I previously gave this a 5 star review and added the caveat that I was not using these roughly in any way and that they were purely indoor so that may be why I, unlike others, did not experience quality issues. However, now I have begun to experience those issues as well despite the very light use so I really can't keep a high rating on this. About a month ago one of the weights developed a tear (in an area that doesn't really experience a lot of stress on the material, so I have no idea why) and was leaking the metal pellets that are inside. This is on top of the general quality concerns I was willing to ignore like the reflective material lining the edges easily wearing off. I haven't even owned these a full year and while I have owned them they have been used only 2-3 times a week at most. At the time I noticed the issue it had maybe been 8 months since I bought them. Product just isn't durable at all. This is in regards to the 5lb weights, maybe the lighter weights don't experience these issues as frequently. I wouldn't suggest these at all.
