It would have been helpful if you mentioned the price of each product; without it, one is required to check out the link, which was perhaps the idea. I wanted a complete and independent review. Having to go to the site to get the price defeats the purpose of the review.
I had the 1st one and I really like it. The down side why I ended up tossing it out. I have a cat and he just chewed all sorts of holes in drain tube. I tried silicone to seal it up at the bottom, but it only created more issues. I really like it, but now I want something that works great, but more cat proof.
