Review (2/5): OK, but can't use it in most places
I bought this item solely because I needed a portable oral irrigator, which allows me to use as much water as I need without refilling the water supply (which would normally be 3-4 times with my countertop unit)
I have been staying with family longer than anticipated, so I made the mistake of not bringing my countertop oral irrigator from home.
A wrench had to be used to loosen the faucet tip, where you attach the irrigator. Since I am at someone else's home, I can't keep asking them to produce a wrench each time I want to use it, and they won't allow me to keep the unit attached.
So, when I spent the night at a hotel, I took the device with me. I was hoping that every faucet tip is not as securely attached as the one at my in-laws. No such luck.
Every other hotel (I tested 3 so far) I have been to is the same. My husband travels with me, and even he could not loosen the faucet tips by hand. Unless you are willing to carry a wrench with you, this oral irrigator is not a good choice for portability.
As far as the function, it worked ok the one time I was able to use it. The pressure was so-so but I didn't really expect that much from a portable unit.
I had some trouble getting the temperature right. Every time I would switch back to faucet mode, the irrigator would run only cold water afterward, until I turned both spigots off, reopened them, then waited a few seconds. However, that may just be the particular faucet that I used.
In sum, I am unable to use this product. It's a shame that I cannot recommend it, as I had high hopes for it.
