I bought this to replace a 12 year old butterfly shape vac head where the bristles had worn down. This head works great on my fiberglass pool. While it does not have a spring to help keep the head down like my previous vac head, the weights on this one do the job. The construction of this head appears to be sold and I expect it to last many years.Would recommend this product to my friends.
