The strap is really helpful. I've got this product only to use the strap with the other type of sling(the one for fractured collar bones). I use the strap during the night. It helped my son not move his hand during sleep. The shipment was very fast.
Bought this for my 5 year old after a fractured collarbone. Easy to put on, great fit, does exactly what it's supposed to. In addition to that, customer service was excellent. I rang a few times to ask different questions, made an error in my order and every time they just helped me out without a hint of annoyance. Exactly what a flustered mum needed.
Great fit, comfy and quality exactly as advertised, Delivered quickly
