Toothbrush Replacement Heads for Waterpik Complete Care 5.0/9.0 (CC-01/WP-861), STRB-4WW, (4-Pack, White)

They do not fit Waterpik Complete Care WP-861W. Second product I've tried, same result. Can't jam them on. I'm afraid I'll break the toothbrush.

I have a water pick toothbrush and these heads wouldn't fit. I didn't need item replaced.. I needed refund. After 2 attempts and $$ held up I'm frustrated!

According to the description these should have fit my Waterpik Complete Care 9.0 (CC-01) but they do not. The hole for these is considerably smaller than the OEM brush heads.

This seller is great, awesome product, super price, nice add-on service but, best of all this it's the ONLY package in the entire history of orders that I have placed with Amazon that actually delivered the item in the time frame described. In this case, it was the next-day delivery, and sure enough, they made it happen. On other orders that promote next-day delivery (with Prime) I have received packages as much as five days later than promised. This store is on my favorites list and will be my first choice to fulfill any order in the future! Great job and THANK YOU!

They fit extremely tight in the water Pic handle. When pulling it off the inside of the brush head stays on the water pic handle. I have had this happen to 3 of them so far. I used Loc tight adhesive on them. I used one of them and it still came appart I had to throw it away. I am not optimistic on how long the others will last.

this brush all this product last about a week to 10 days and then it falls apart what a scam

Need pliers to pull off and on toothbrush; doesn't seat as well as Waterpik brand, but at great savings it works. Quality not as robust as old Waterpik models, but then nothing is anymore.I change brushes every 4 months instead of usual 6 and it holds up until then.

I’m sorry but I won’t try to save a couple bucks next time. The bristles were so painful it made my gums irritated and bleed. I ended up throwing the remainder of the package away to buy real waterpik refills.

I was happy to find these brush head attachments as they are very difficult to find for some reason for water Pik.They hardly go on but do only half way. They are usable regardless. What I don’t like particularly is that they are a bit thick, bulky so when using brush head the plastic part at the back the adjacent teeth. This could chip some teeth if not careful.

They fit but it's tough. My wife and I share one toothbrush and we remove the brush after each use so the other can use the unit. This was fine for the original heads but these replacements are too tough. My wife isn't strong enough to remove the brush head. I have popped the insides off trying to remove the brush head.They go on with some effort. They function. Removal is a pain.

Works with model as promised. Good value and quality.
