These are a great upgrade from the pin and pipe safeties that came with my rack. They are easy to move and function as they should. The main draw back is the extra slack in them but it's not a deal breaker.
These do the job and will keep you safe.The main draw back is that they're inconvenient. They're better options out there but those do come with a much higher price.
These collars are cheap and come with a lot of equipment. These seem to work but can become stretched out over time causing them to not hold as well. I just think there are better options out there.
These are a decent looking kettlebell for the cheap price. The handles get pretty big as the weight of the kettlebell goes up which works the grip considering how smooth they are.
