The Onlyone flosser that I received from this deal does not have a USB C charging port. Previous comments mentioned that it did and it was part of the reason that I ordered it. So heads-up for anyone else reading the comments looking for USB-C.

I have one of these. It works well, but the water reservoir is small so realistically you need to refill it at least once to do a full run.

Having bought a few cheap water flossers thanks to slickdeals (to use and give away as gifts), I would get this over the Bitvae. The Bitvae C6 that I got used a proprietary charging cable (which sucked when forgot to pack it for a trip), and the C5 might also have that issue plus it has a smaller tank capacity. Also, I couldn't find how much water pressure the C5 can generate, but this says it can provide 50-150psi which is on the higher side for battery operated dental flossers.

If any good at all, this is an excellent deal (my old Water-Pik was nearly $40., years ago). Repped.

My son uses this model daily and it works well, especially for this price.

Incidentally, there is at least one other brand discounted to $9.99 for a limited time & doesn't require Prime nor coupon code.

I bought this. It seems fine but I can't compare it to anything else.

I preferred this one over the other common deal since it has USB C charging port.

That hasn't been my experience at all. The reservoir holds enough water for the two minute run time and then some. Also, you're supposed to empty it after each use, so having a bunch of extra water sitting in there seems like a waste.

Thanks! I did get this one based on the charging port and capacity last Sunday but you also raised some other pros.

Bought this at this price a few weeks back, so far so good, my first venture with a water flosser

If you want a special treat, add a tiny bit of mouthwash to it

Hows the quality and battery life?
