The quality of construction is not good, my straps broke over time and it is definitely not suitable for running... it gets the job done... also, there is a possibility that it might be too big for an average person as I am 1.95 meters tall and it is too large for me

It's fine, you just need to wear a shirt underneath otherwise it makes a scratching sound. As for the fit, it's more than enough in terms of length with the Velcro straps. (1.82-120 kg)

Overall low build quality. The weights contain sand. I can't justify the price, but it gets the job done.
Note, it is wide. I am 1.90m, 80kg and I can't tighten it enough to not move unless I wear a very thick jacket underneath.
