Which is better for braces?

The Nicefeel lists an orthodontic head among its 7 tips, so it is the clearer pick for braces. The COSLUS listing does not specify which tips are included.

Is the COSLUS worth the extra $5.67?

It buys 12 pressure levels instead of 10 and a 4.4 rating versus 4.2. If you want finer pressure control, yes; otherwise the Nicefeel saves money.

Do both hold the same amount of water?

Yes. Both have a 600 mL tank, enough for a full flossing session without refilling.

Which has more pressure settings?

The COSLUS has 12 levels. The Nicefeel has 10, spanning 30 to 125 PSI.

Are either of these cordless?

No. Both are corded electric countertop units that plug into a wall outlet.

Neither listing states a lifespan or written warranty, so there is no documented durability difference. The COSLUS has the higher rating from more shoppers.
