just what I needed. work great. Buy these heads, they are made in Netherlands. Costs a little more, butmuch better than the generic no name blades

Arrived quickly. They are doing a great job for me. Very good, close shave.

Why did you pick this product vs others?:Not as sharp as I would like but still gets the job done.

Tried some less expensive heads, they shaved worse then my old blades. Bought these and I am now getting a quick close shave

I was afraid installing the new heads was going to be difficult, but I was astounded with how simple it was especially after reading some reviews written by other customers. The heads literally dropped right into place & I was back to getting a clean shave within minutes. It was like using a new razor again. Thank you!

I have been using these shaver replacements for over 5 years with no issues!

Very good quality. Sharp. Easy to install. I, order a new set about once a year, to assure continued smooth shaving.

Don't waste your time trying any of the various "knock-offs"I made the mistake of purchasing non-OEM blades, and even an entire new head with blades in it. Terrible results!I just slipped these blades in and my Aquatech rotary shaver is shaving like new again!
