Water piks have made such a difference to my oral health (and dental bills!) - I have been SEARCHING for a travel option so I can maintain my good habits. I tried the handheld water pik and unfortunately it was useless. Not enough pressure to get between my teeth, and had to refill the reservoir like five times in a single session, so I sent it back. I tried a sonicare air flosser and that was OK, but I still got food bits out of my teeth when I use my Aquarius afterward. I hoped the sidekick would be the answer, and it totally is. Most important: the pressure is comparable to the Aquarius, I would estimate level 7 out of 10 (I use my Aquarius at eight). It leaves my teeth feeling flossed and clean. For those who care about noise, it is as quiet if not quieter than the Aquarius. Even though wouldn’t mind refilling the reservoir once, I can actually do my whole mouth with one tank of water. I was curious to see if it made a mess because a lot of reviews mention splashing, but even when I filled the reservoir to the very top edge, not a drop went anywhere. The vibration just makes a gentle ripple in the surface. Personally, I am not at all bothered that it doesn’t have a lid. It’s not like a lid creates a hermetic seal, plus its not going to be sitting on my counter for months…and if I DID think dust etc had gotten in there, I would just rinse the reservoir before filling it. The device is smaller than I expected which is amazing for travel. I love the luxury feel of the flosser (the black and copper is gorgeous) - it makes me excited to use it, which is another pus for anyone struggling to establish new routines. Overall, the sidekick totally lives up to the price tag. I’m so happy with it. Now I just wish my countertop Aquarius had the same elegant aesthetic!

Small enough to travel when needed!
I’ve used this for awhile now and it’s works perfectly. Multiple power levels to accommodate the pressure desired!!

I use the waterpic on the left shown in the first picture at least once every day and have traveled with it. It takes up a good amount of space so I decided to check out a travel waterpic, which is the assembled smaller waterpic in that same picture. The second picture shows the four components and the third, the unit in the travel case.
I know how to use a water flosser already and I did not want one that had the reservoir attached to it. I also did not want a battery operated one.
I liked the reviews on the waterpic Sidekick and the size looked nice. When it arrived I was impressed by the packing and that says something about the company.
Of course I wanted to see if and how it worked. It was super easy to put together. I had the setting on three and it was as powerful as the unit I’ve been using at home at the same setting. The quality is great and I was impressed by the weight of the unit. It’s not at all flimsy. The tubing is plenty long to reach from the counter to over the sink for flossing, which was one of my concerns.
I absolutely love this Sidekick and highly recommend it. It is a bit pricey but the quality is there and I expect it will last.
