teeteck 5 Pack Electric Toothbrush Replacement Heads Compatible with Fairywill，Toothbrush Heads Compatible with FW-507/508/551/515/917/959/2011,FW-D1/D3/D7/D8

Delivered quickly and great quality for the price. We all use the same type of toothbrush, so it's nice it fits for everyone in the house

Works as advertised. I'd do business with them again.

I have a Sonic-FX toothbrush, and couldn't find a brand specific replacement. Luckily I saw these and after comparing the pictures they posted with their add I determined that these should work. Happy days, they fit perfectly. They work fine, and for the price I couldn't be happier.

They fit perfect

I like this product because it fits my toothbrush. Good quality

I use these as brush replacements for my Fairywill toothbrush. Gently pull it off and pop a new fresh head in. I've tried other brands saying they will fit my toothbrush but they were difficult to get them to snap in properly. These don't have the plastic covers but that's easy enough to pick up anywhere. The bristles are soft and they work as well as my original set.

Bummed they do not fit. The bristle seem cheaper than my actual brush head but you get what you pay for. Need to return them because they do not fit current tooth brush head (Shaojier brand)

Refills are perfect match for electric toothbrush

Such an easy style to install & replace. This toothbrush is the real OG with fantastic quality & price to go with it. Replaceable heads (any colour, any size) always fit & stay in place. Lots of different settings on the brush that work wonders for your teeth

Niks bijzonders

Well priced. Good quality. I ordered and use it happily. Fits perfectly.

++ Compatibilité parfaite : Ces brossettes s'adaptent aux modèles Fairywill et Seago mentionnés, pas de jeu, bien maintenues. Qualité des poils : Les poils sont doux mais efficaces pour un brossage agréable et performant. Prix compétitif : Excellent rapport qualité-prix, surtout en lot de 5. Durée de vie : Les brossettes tiennent bien dans le temps, pas de poils qui se détachent trop vite. Facile à remplacer : Simple à changer, sans besoin de forcer ou de manipulations compliquées. -- Pas d'indicateur de remplacement : Une bande d'usure colorée pour indiquer quand changer la brossette serait un plus ?? Pack standard : Pas de variété de dureté des poils, dommage pour ceux qui préfèrent une option plus souple ou plus dure. Emballage : L'emballage pourrait être plus écologique, beaucoup de plastique inutile.

Worth the money I paid
