Well I was finally able to get around and set it up and use it.
The unboxing was pretty straight forward and it was pretty easy to set up. He has a set up video on you tube which was nice.
It seems as though he thought his product through nicely. You have the option of using a battery or a powered plug. The pole extender is nice for those who have taller tanks. Being able to turn it into a sand vac is a nice feature (but I haven't used that yet) I would have like to maybe see a more powerful pump, however it worked fine so it is not needed.
It works great on your rocks, and getting into those tough area's but does not work well on your sand bed. I was trying to get some Cyanobacteria off my sand bad, and a small rock got caught twice in the pump propeller. Even though its pretty easy to unscrew the 4 small bolts and clean it. Its not worth doing over and over.
However I think the sand vac would work great on the sand bed so I am glad he has that attachment available
The one thing that is missing is a safety lock to keep kids from turning it on. I have small kids and since it has a drill bit at the end of it, you really have to make sure that you don't leave it under your tank or in a place that kids can get to it. It looks like a fun toy for kids and I can just see them turning it on and playing drill master on my acrylic tank or each other.
At the end of the day, it is our goal to spend as much time as we can enjoying our tanks instead of always maintaining them. Any tool that helps speed up the process of maintenance and helps us to have more time enjoying our tanks are usually really worth it. As is the case with this product.
Is $70 a high price, I am fine paying that price and wouldn't have a problem spending more than that for what it does (as long as it doesn't break on me).
It's great to see people coming up with better ways to assist us in maintaining our tanks. I don't remember 20 years ago if anyone had a magnet to clean your glass, but the $70 I spent on my hammerhead float magnet a few months back was definitely worth it.
I had some hair algae on my overflow and it cleared up pretty easily, It did stall a few times but still worked great. below are a before and after pic.
