I love these toothbrush heads that I purchase from boots. I have used Philips for along time, and had 3 electric toothbrushes. So far they all have lasted well, and as you get maintenance included - any problems are repaired or replaced which I found quick and reliable. Especially as you need your toothbrush everyday. Anyway I love these toothbrush heads, best yet from Philips. Very happy customer.
