ARM & Hammer Spinbrush Pro-Clean Replacement Brush Heads, Medium 2 ea (Pack of 3)

I have been using the Spinbrush electric toothbrush for some years now, and I appreciate its effectiveness in cleaning my teeth along with its economy of use. I replace the brush head on my toothbrush approximately once each month when the brush color indicates that the bristles are worn out and can no longer clean effectively.I purchased five boxes of these Spinbrush replacement heads (a total of ten pieces). However, after going through about half of my supply, I find that their longevity is variable. So far, I have had three brush heads fail -- they simply stop moving when placed against my teeth, motor running normally. Replacing the brush head with a new one typically resolves the problem, but not always for very long. And yet, other brush heads in this group work for their normal expected lifespan.The failed brush heads are clean, well-rinsed and never clogged with toothpaste. They still have clear freedom of movement when I operate their mechanisms manually with my finger. Subjectively, the internal spring on the failed heads seems weaker to my touch as compared to a new, working unit, but honestly, it's hard to tell. I have tested the failed heads on two different series handles (motors) with the result that the problem follows the individual brush heads. I have not had this problem with brush heads sold as pairs in (more expensive) blister packs at my local retail store (these brush heads arrived in pairs in small cardboard boxes with molded plastic inserts).Just a bad manufacturing day for Spinbrush, or are these brush heads poorly-made counterfeits? I can't tell. Let the buyer beware.

I needed to purchase some replacement heads but did not want to have to replace the whole toothbrush with it so I decided to give these a try and they are fine and fit my spinbrush Pro as perfect as the original one that came with my toothbrush fit.

Deep cleaning/Good for Traveling.

Yesss cheaper than replacing tooth brush in comparison to dental bills when you use a normal toothbrush. My dentist asked me what I use so he can recommend it to his other clients. This is what I told him

I have an Arm & Hamer spin brush that was purchased a few years ago and thought this brush would fit my unit. It fits but does not go all the way around for it to line up straight on the unit. I just have to turn the handle when brushing and it works fine, otherwise I would have given it 5 stars.

These were reasonably priced for replacement heads. Quick delivery from Amazon. I'd order them again in the future.

Hygienists always ask what brush I use because I never have much tartar on my teeth. The Spin-Brush with the medium bristle is the reason. Spin-Brush was a P&G product that was sold to Arm&Hammer. They didn’t change anything. Great brush action provides circular and back and forth motion. Have used them for years.

Before I looked on Amazon, I used to buy this pack at Walmart. Looks like Walmart (at least my store) no longer sells them or the toothbrushes. So I started looking on line. Found them at Amazon for a little bit less and have had no problems - even with re-orders! I love the Spinbrush Toothbrush, they the brushes do wear out - usually lasts 4-6 weeks then I replace it not only because the brushes start to soften, but for Health Reasons too! ENJOY!

Battery factory installed is a bit weak. Ordered 2 but only using one, so wondering if I should remove the batteries from #2. No accompanying advice on this. Have used these brushes before, but now not available off the shelf. Best electric toothbrushes ever!!

Items arrived as described :) Thanks!
