1000/10 Highly Recommend
My daughter purchased this toothbrush brush for my from Sprouts. I was so impressed I came to Amazon to purchase one for my husband and sons. This is the BEST toothbrush I’ve ever owned. When I use this toothbrush my mouth feels like I just left the dentist. I’m fighting periodontal disease, so I love that fact that I’m able to massage gums while brushing my teeth. The large head makes it easy to reach my molars. Im so glad I found this toothbrush, Im never going back to my old toothbrush.

Finally—A Toothbrush With Real Bristles! Everything Else Feels Like Plastic Junk!
I don’t know what’s going on with toothbrushes lately, but everything out there feels cheap and flimsy—the bristles either fall apart or feel like stiff plastic. This RADIUS Big Brush with Replaceable Head (Right Hand) is the only one I’ve found that actually has real bristles and feels good! The bristles are soft but dense, so they really clean without feeling abrasive, and they hold up over time. Plus, the big, ergonomic handle fits comfortably in my hand (perfect for right-handers), and the replaceable head makes it eco-friendly—no more tossing the whole brush! This toothbrush honestly makes me look forward to brushing. It feels like I’m actually getting a thorough, gentle clean, not scraping my gums with plastic sticks. Amazon had it in stock with fast shipping, and I’m so relieved I found it—I might just stock up so I don’t have to go back to those junky brushes again. If you’re sick of the plastic-feeling toothbrushes flooding the market right now, this is the one you need. Trust me.

AWESOME!!! BEST TOOTHBRUSH I HAVE EVER USED - - BY FAR!!!
I buy these toothbrushes with the soft bristles about three times a year. THEY ARE THE BEST I HAVE EVER TRIED! USING THEM IS an AWESOME EXPERIENCE! The brush head is large and gets into every corner of my mouth with ease. It also makes cleaning (brushing) my tongue and my gums a quick and easy job. The bristles last forever it seems and using them makes my mouth feel truly clean and refreshed, in no time. I have used Radiius Toothbrushes for more than ten years (they were called SOHO Brushes then, as I recall). They have reduced my bad experiences in dentists' offices. To me, they are more thorough than today's electric tooth brushes. After brushing my teeth and gums with them for months, I use them to clean the grout in my shower, the seam where my sink rests on the countertop, and other odd jobs around the house. Try them; I believe that you too will love them.

Best toothbrush ever
My favorite toothbrush. Haven’t had a cavity since I started using this brand almost 10 years ago.

Great for brushing the dog's teeth!
I bought these because of the large size to brush my dog's (and cat's) teeth along with a special pet-approved toothpaste. The toothbrushes the vet gave me were so tiny that I would often miss or my pets would quickly move their heads and the small brush head would slip and I would end up accidentally brushing the side or top of their heads instead! The large head of this toothbrush is a great size for a medium/larger dog's mouth and it's big enough to cover a few teeth at once. Although they are too large to really fit a cat's mouth, if your cat likes to rub against things with her mouth partly open, like mine does, this might work. The larger size makes it more likely that while she is rubbing against it, that some bristles will get to her teeth, and it's soft enough that if some of the bristles brush the side of her face, it's not a problem. Just make sure to use a toothpaste approved for your pet!

Best toothbrush
The size can seem a bit overwhelming at first compared to regular toothbrushes, but the handle helps with ease of hold. The bristles are soft but firm enough to provide a thorough cleaning. I love the green color, but having an option to change is nice, they have quite the variety. If you’re looking for sustainable choices, buy the one with the option to replace just the head of the brush.

Testa della spazzola un pó troppo grande ma comunque accettabile. L'impugnatura invece, seppure anatomica, risulta troppo ingombrante e difficile da maneggiare.
