Review on Alfie Pet 2 Piece Checker Aquarium by Marisa Lynn

First of all the drip tester is upside down in the photos. Also, this is a means of checking the drop of bullets. There's nothing special about it and it works great for me. The suction cup holds well, there were no problems with it. The glass is not the best quality but you can see it in the photo. The shape and finish is rough and not of the highest quality (almost like factory seconds). However, you get two for the price of one. So if you need something to just check your CO2 levels regularly, this will do the job. Getting the solution into the drop tester is pretty easy, but you'll need an eyedropper to get it out.
