AU-300D Ultrasonic Toothbrush Replacement Brush Heads - Soft / 2 Count

I bought the Smilex Ultrasonic toothbrush a few months ago and am very pleased with it. I use it with either tooth soap (or Dr. Bronner's liquid soap) or baking soda. I also started oil pulling and this combination has made a big difference in my oral health. I wish I had known about it years ago and probably could have saved some teeth. This toothbrush is definitely worth its price and I highly recommend it.

I bought these the same day I bought the Smilex toothbrush - I thought the two would go together. They don't. The toothbrush I got was White with a GREEN handle, not White with Gray handle (as the description says). They sent me the wrong toothbrush, but I didn't realize it at the time - it was a Smilex toothbrush and I was happy with it. However, now it's almost 6 months later and I was going to change out the toothbrush heads, but I discovered that the replacement brushes don't fit the White with Green handle toothbrush, so I'm out $20. Very disappointed with Tools for Living/Amazon for screwing up the original order to begin with and leaving me holding the bag. I ordered the other brush heads today - we'll see if they fit this green-handled toothbrush. By the way, I really like the toothbrush, I just hate getting screwed by the vendor on the brush heads.

I purchased the Original Ultrasonic Electric Toothbrush by Smilex (model no. AU-300E) and a pair of replacement brush head together. However, this type of replacement brush head (model no. AU-300D) does not match the tooth brush. The ORIGINAL brush head (the one on the left in picture) does NOT have the lock ring as the REPLACEMENT brush head (the one on the right) has. The inner diameter of the replacement brush head is too small to be installed on the tooth brush.

The Smilex works well but I still miss my Ultreo. The brush head was much better than the basic head that you get with the Smilex. The Smilex toothbrush is basic overall compared to the Ultreo, but they went out of business and I need another Ultrasonic toothbrush. Nevertheless, the Smilex works well and blows away the Sonicare Diamond. I never had luck with Sonicare, although my husband likes it. Having said that he never tried a combo toothbrush. The good news is my teeth feel almost as clean as after a dental cleaning with the Smilex. It removes some staining but not all, also adding to the 4 stars instead of five.

Excellent and so is the Smilex tooth brush.This is ts the best tooth brush anyone could own. It really works!!!!!!!!

The replacement heads are for quarterly use as recommended.It was good to see the English label on the back as all otherf print was in Japanese.

It was a waste for me to buy these replacements because the unit cracked.

Don't like the Smilex machine. Waste of my money
