It broke within two months.This lasted a few months before the head cracked, rendering it unusable.Love this product, easy to assemble and it’s worth every penny. Very sturdyWe all love this! It is set up in our living room for now. We all have a boxing match at least once a day and let out our frustrations due to all the Covid mess and being home all the time.I loved this reflex punching bag, still do, but mine will not allow me to move it up and down anymore to adjust to my height. It like rusted or something and I've had literally had everyone I know to try to help me turn the knob, but no luck. I purchased this last year so its too late to ask for replacement, but oh well.It’s a great bag and easy to put together. The spring was missing and some parts but the seller was really helpful in getting the missing parts sent out.Bought this for my son. He really loves it. I do to. It's a workoutVery useful and great quality. If you fill it with water it barely moves, and the spring support looks great quality. 100% recommended for stress relief and great workout.
