This saved me during tax season! I would like more options for retailers, but other than that, I definitely would recommend this book to someone else.

Safe for invertebrates and scaleless fish. Easy to use and excellent instructions. It does stink but the smell goes away almost immediately after being added to the tank. Much better than the Tetra products. Keeps my tank sparkling and my fish are healthy & happy. I'm definitely a customer for life!

Looks great, easiest install (if you even call it that you just screw it in) ever. As far as downgrading radio reception, couldn't really tell a difference to be honest. I don't listen to the radio that much anymore these days anyways. That's what pandora and Sirius are for! I gave it 4 instead of 5 cause it's a little pricey for the piece. I think 15-20$ is a better, more reasonable price. 25$ is a little steep for this.
