Truly soft Most toothbrushes that I have purchased say they are soft but feel medium or hard, but the Glisten toothbrush is one of the softest toothbrushes that I have used. The bristles length, head size, and handle are all well designed and are not too big or too small. I’m definitely recommending this toothbrush to anyone who wants a truly soft toothbrush.

Exemption Form was a fiasco Exemption Form was a fiasco. Sent 4 times and still wasn’t right. Never received acknowledgement of shipping or tracking info. Called and someone answered the phone with just Hello. No company name. Shipment finally showed up with no help from you. Quantum has never been so bad.

Upon delivery the boxes were very… Upon delivery the boxes were very ragged. The first box we opened there was 10+ that had broken zippers. I need to do another big bulk order within the next week, but am reluctant to do so with the order I did receive this week.

Great toothbrushes. Great company. Patient's love the Quantum brushes. They are top quality and Quantum has the best customer service.

My favorite electric toothbrush head I use my Sonic Pro much more now that I discovered Quantum Labs Ultra Sensitive brush head. With the original heads, I was only doing it at night, and on the medium intensity setting. Now I use it morning and night, and on full intensity. Thanks to my hygienist for the sample! I received the order in seven days. It was kinda "old school" in that I didn't get and email with tracking number it shipped, but it did ship promptly after all. Only downside is that I had to buy 48 heads, which, even if I change once a month, will last longer than the toothbrush.
