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 only floss I'll use
I bought this floss at a last attempt to fix my dental habits. Other floss tends to cut at my gums, or be too thin to even do anything. I was attracted to Burst because of the "expanding" technology and the fact it was a reusable container.
Like other reviewers said, I had a hard time putting the bobbin in at first but after looking it up it was fine. The packaging also included instructions on how to floss which is helpful for people who need to brush up (lol) on their skills.
Pros: The flavor is a nice, traditional mint. I like that the string is black so you can see plaque. The floss is a nice, grabby texture that really pulls items out from your gums and holds onto them.
Cons: Not too happy about the price and refill price compared to other floss, but it's worth it to me if it means flossing regularly!

Nice dispenser, great floss
Review for BURST Refillable Dental Floss Dispenser Set - Juniper Berry Scent
Nice work, BURST! You may have gained a return buyer with this floss.
I purchased this solely for the refillable dispenser. On that end, I'm very happy. The dispenser is pretty easy to fill, and very easy to use (once filled). I didn't see many other floss dispensers on the market, but I'm very pleased with BURST's.
I've been very happy with my previous floss (Dr. Tung) and I wasn't looking for a change. But since this dispenser comes with floss, I tried it out and I am super impressed. It has a lot in common with the Dr. Tung floss: it has the woven, cloth-like feel that expands when it goes through your teeth. I find that BURST floss feels slightly thicker than other floss, but not so thick that I have any difficulty moving it between teeth. I haven't had any shredding or breaking issues with the BURST floss. The flavor is very mild and refreshing.
If you're looking for a refillable floss dispenser, I recommend BURST.

Floss leaves mouth super clean!
I’ve been really irritated by tooth paste co’s dental floss products either being too small/not lasting very long or too waxy/sticky, too minty so I searched for better dental floss and found it with BURST CHARCOAL FLOSS! The floss is black/coated by charcoal and has a smooth non sticky feel to it with a nice subtle mint flavor. Putting the bobbin in the refillable container (another plus reusing container) was slightly tricky because it doesn’t pop off easily and instructions were somewhat vague. After watching a Burst video on YouTube, you turn the container upside down & squeeze the edges w/ tabs & it pops off. The bobbin that came with the kit looks smaller than the pix, we’ll see how long it last. Actual flossing was great, the floss really flattens or expands as it’s pulled between teeth. The floss being black shows and cleans even more gunk from between teeth/gums leaving mouth fresh and super clean. It’s exactly what I was looking for, I highly recommend this product. Only drawback is the smallish size of initial bobbin, took one off star but that can be remedied by Burst co, should more ppl agree & comment. Happy flossing!

I love this case. It’s functional and very pretty.
I found out that the dental floss I’d been using for years is coated in PFAS and other forever chemicals, so I switched to brand that didn’t have any of that. The obvious upside is that I don’t have to worry about those chemicals anymore and get great expanding floss, but the floss comes in a paper case. That case is functional, but I floss and brush a few times a day so I knew that I wanted something that was more durable. I saw this case and fell in love when I saw it and after a couple months of using it, I’m still in love with it.
It’s easy to refill, durable and so pretty. Overall just frustration free. It adds a special touch to my flossing routine and elevates that experience for me. The floss that comes with it is great too. It was my first time using charcoal floss and I liked it.
I kind of wish they offered the case in a variety of colors as a standalone item, so I can chose my own floss (or a mix to try out the different flavors), but that’s not a big deal and for take away from anything.

A better floss
The wife loves this. It does remove more plaque than other floss. Its woven so it appears to grab more gunk and plaque. It is also thicker so it fits tighter between the teeth. Good product and worth the $. Would recommend.
