Ben, I don't disagree. Personally, I'd go with the Black Magic. The Biogard one I have from a zillion years ago was as well-made, if not better, than the Black Magic, but I don't know if it's available. Luckily, they are very simple gadgets and harder to screw up. I just offer options.

The Pool Blaster is a far more expensive option but as I said, I'm on my second and I wouldn't be without it! I have not used a suction side vacuum in 8-10 years, not since I got the first when it was still called a "PoolBuster" (to mimic DustBuster--I guess they got sued for using a similar name).
