Order on app for an extra $10 off APPONLY10 (First-time users)
Cheapest I've seen so far on Sonicare. I've been using my Diamondclean for 2 years now and have been great!
The main difference between the 2 is DiamondClean has more bells and whistles (app connect, wireless charging, cup etc)

Just buy the Oclean X Pro and get a better toothbrush for half the price of the Diamond Clean. I've owned two Diamond Cleans down the years but now have the previous gen Oclean X and it's far superior. The battery life alone is about 4 times longer.
