What every best has:
In tests, most pets like being brushed with the Pet Groom Pro ionic cleaning brush (especially if they like being brushed anyway), but some hate it. One review notes that the buzzing may irritate some pets, and if the pet wears an electric-fence shock collar the brush may set it off. Testers like the Pet Groom Pro's easy-clean feature -- just pop off the faceplate and the accumulated hair comes with it. As for removing loose hair from the pet, reviews are mixed: Some say the Pet Groom Pro pet brush does a good job, while others say their regular brush does better.
We found several TV news stations that tested the Pet Groom Pro ionic cleaning brush. KDKA in Pittsburgh gets a local pet owner to test the brush on both dogs and cats for two weeks, and the website includes the original video segment. Seattle's KOMO doesn't post any video, but its review quotes two pet owners with different opinions about the Pet Groom Pro brush, and it is well written. Other TV reviews are briefer, but still helpful.
