Still Working Great After a Month of Use
Color: Beige
I’ve been using this trimmer for about a month now, and the overall experience has been even better than expected. The device is very versatile, and the different attachment heads make it convenient for various grooming needs. It’s gentle on the skin and trims smoothly without causing irritation or cuts. The waterproof design makes cleaning quick and easy, and a single charge lasts a surprisingly long time. It’s also lightweight and convenient for travel. The battery display is very useful since I never have to worry about it suddenly running out of power. The overall build quality feels solid and the motor is fairly quiet during use. After a month of regular use, it still works great with no noticeable drop in performance or battery life.

Perfect Size and Gentle Enough for Small Dogs, Makes Brushing Way Easier
Color: Macrobrush Kit, Color: Macrobrush Kit
This toothbrush ended up being a great fit for my small 8 lb dog. The head is small enough that I can actually reach both the outside and inside of her teeth without feeling like I’m poking around with something too big or awkward. That alone makes a huge difference because most dog toothbrushes feel oversized for small mouths. The bristles are soft and gentle, which my dog seems to tolerate well. She doesn’t fight me when I brush, and that’s saying a lot because she usually has zero patience for grooming stuff. The 360-degree design helps too, since it cleans more surface area with each pass instead of needing to angle the brush a million different ways. It’s easy to hold and doesn’t feel flimsy, and I like that I can get a decent clean done pretty quickly without turning it into a wrestling match. If you have a small dog and struggle to find a toothbrush that actually fits their mouth comfortably, this one is definitely worth trying. It’s made brushing less stressful for both of us, which is really all I can ask for.

Good Brush but be Careful
Color: Macrobrush Kit
Works better than most dog toothbrushes I've tried. My dog broke the brush head on one, so you have to be careful.

My puppies love this toothpaste and toothbrush
Color: Macrobrush Kit, Color: Macrobrush Kit
So easy to use! My boston terriers love having their teeth brushed with this 360° toothbrush and they love the taste of this toothpaste. When I get it out they come running, no resistance at all. This is soft enough for my teething puppy and seems to feel good on their gums and teeth coming in. The brush is small and perfect for 16lb puppies mouth and teeth. Have been using this for almost a year and it is definitely been worth the price for a slightly angled and made well. Im confident that their for puppies!
