Electric Toothbrush Replacement Heads 10 Compatible with Fairywill FW-507/508/551/917/959, FW-D1/FW-D3/FW-D7/FW-D8, YUNCHI Y1 - Dark

I have been using these for a couple years. It’s nice that when you want to replace your toothbrush head all you gotta do is pop one off and pop another one on. They work very well. It’s nice to have my back on hand.

My husband goes through these very quickly, it’s a good price for a good amount.

These brush heads are very strong,durable and last more than 65 days each usage

Great value for money! Fast shipping! Happy customer.!

Works perfectly!

Fits great! Excellent price.

these are not as durable as the original ones from fairywill - they tend to fray a lot faster.I would not purchase these again, but there are no other options since fairywill has disappeared off of amazon.

I have purchased this three times. The third time, all 10 do not fit my toothbrush anymore- their sizing must have changed.
