16 Replacement Toothbrush Heads Compatible with Philips Sonicare Toothbrush, 7900 3100 4300 5500 Plaque Defence Brush Head with Densely Clustered Bristles - Standard Sonic Brush Heads - Black

These are a great alternative, fit well! A little tight to begin with but do fit and work well with the power when one. Great value for money.

These are working really well. At first they are a little hard to get onto the main toothbrush. A slightly snug fit; however, once on, they work great, and I have no complaints. They clean well with bristles that are not too soft, but firm enough that i sense they will have good durability. The price i paid makes them very good value for money.

Very nice and soft.

Thought I would try the ultrasonic tooth brush for a change and was quite surprised how thorough it was ! Takes some getting used to , but after a few days it felt really good and I was surprised how good it was ! Not cheap but I think it was worth the price after seeing the results after 4 to 6 weeks

Great value replacement heads, fit well, clean well, seem to be lasting well

Great bit of kit works perfect with Mt toothbrush

these toothbrush heads are smaller than the one that was originally on the Philips Sonicare, fit alright and still do a job.

Realy please with my item the tooth heads whear really good value I will buy them again
