I already purchased one python hook from Aquarium Co op. Really happy with it it has made water changes so much easier. Thats why I decided to purchase another one to speed up the water changes even more.
The only complaint I guess is that I had to add a shut off valve to the Python Hook but that's it.
Best invention ever for filling your aquarium up...NO MORE BUCKETS!
This thing is awesome for filling tanks and allows you to be able to walk away or do something else in your fish room, without having to worry about the hose falling out of your tank and spraying all over the place. Simple to use, makes tank filling a breeze.
After filling my tank with the regular gravel vac end for a few months I finally made the mistake of not watching it. Walked in to a soggy floor and realized that this product might be useful after all. Purchased it and haven't regretted it once.
Elimnated the need for clamps to keep my hose in the tank when refilling after a water change. Also, I noticed two other reviewers said that it didn't come with a shutoff valve. I was a little confused, when paired with a python hose, you can detach the syphon head and attach the hook, the shutoff valve on the python hose with shut the water off the same as with the syphon. Hope that helps someone.
