Frequently Asked Questions

At what age is my child ready for a belt-positioning booster like the Tanza?

The Tanza is intended for children who have outgrown their forward-facing harnessed car seat and weigh between 18 and 45 kg (40–100 lbs) while measuring 110 to 145 cm (43–57 in) tall. Most children reach this stage around age four to five, but always check your current car seat's outgrown limits first.

Can I install the Tanza without the UAS connectors?

The Tanza is designed to be used with its rigid UAS connectors for a secure fit. Refer to the product manual for your specific vehicle compatibility and installation guidance.

Is the Tanza allowed on airplanes?

Belt-positioning boosters rely on the vehicle's lap-and-shoulder belt and are generally not certified for aircraft use. Check airline policies before travelling.

The strips work great!
Size: 40 Count (Pack of 1)
It's a great product that works. I left the strips on for 2 hours. And my teeth were so white, I decided not to use the light. I drink 3-4 cups of strong coffee everyday, and they are still really white (after one application over two weeks ago). My gums were a little sensitive after 2 hours, but that only lasted a few hours after usage. Just be aware if you leave on more than 60 minutes. Then brush and rinse really good. I use their "brilliance" tooth paste as well.

DOOOO IT (see before & after pics)
Size: 40 Count (Pack of 1), Size: 40 Count (Pack of 1)
My dentist actually recommended this in contrast to the products offered in office! So I had to try. I was especially interested in a whitening system that would not sacrifice effectiveness for gum sensitivity. Not only could I see instant improvement, but I had no gum irritation whatsoever, not even next day. So that's the two big things that exceeded expectation. A few drawbacks though - (1) Instructions were unclear as to how long to leave the light on, & I didn't realize until after mixed Internet recommendations & testing it out blindly that it automatically times out after a few minutes; (2) the product unfortunately outlasts the light's battery life, so I had to find a $16 replacement LED on Ebay, & (3) the adhesive will strip your dental work fyi. Not cool, but still overall beneficial as a whitener & hundreds cheaper than true, professional whitening. BTW this before and after were taken within a month of each other.

Amazing transformation!!
Size: 40 Count (Pack of 1), Size: 40 Count (Pack of 1)
I hardly ever write reviews, but this product has transformed my life. And imonly on the forth day. After the first day it removed so much of my yellow stains. I can't even think about how white my teeth will be when I finish. I called my dentist to see how much it would be to whiten my teeth and she said $500. Are you kidding me? So I ended up trying these white strips instead. I'm so happy with the results after only a few days!! The first picture is the start, then after using the strips 1 time, then after using the strips 3 times. I had to come and post a review immediately. The pictures speak for themselves. And not to mention that I usually have sensitive teeth. So far my teeth don't hurt while using. I will definitely use this product every year. Thanks Crest!!
