Fiber to the Home is far from the only and most efficient technology to deliver Gigabit Internet access to subscribers. Retrofitting an existing (brownfield) Multi-Dwelling Unit (MDU) with fiber is complex, highly disruptive and expensive. With the G.hn Aggregation Multiplexer (GAM), Positron Access addresses the key challenge of delivering Gigabit Internet access to subscribers in MDUs as well as dense Single Family Unit (SFU) homes by leveraging the existing telephone or coaxial infrastructure to deliver near symmetrical Gigabit services at a fraction of the cost of alternatives.

4 year old approved!
Color: Lightgreen, Color: Lightgreen
Love that this is a complete set, down to the wall block for the charger!
My daughter is 4 and absolutely loves this set. I personally feel like the toothbrush head is a tad small, but it does do the job well. Its a soft brush head, with plenty of replacement heads. The toothbrush and the flosser both arrived fully charged, and so far we havent had to recharge it, but we're only a few days in. So, it seems to have a pretty good battery life so far. (I will update my review if anything changes on that aspect)
The toothbrush and flosser both stand upright independently on the counter, without tipping over.
The water flosser is hard fir my daughter to do by herself. She sprays water everywhere, as theres several buttons on it and she cant seem to remember in time which button turns it off. I help her with flossing and its been going fine.
Whether youre on high or low the water pressure is not too hard for a kids mouth. In fact, I think the low setting does nothing but rinse the mouth and basically teach the habit of flossing. We use the high setting and it does and OK job. I am a little old school though, and feel like nothing will top a good ole dental floss flossing, but water flossing is a safer route to avoid cutting gums or getting floss stuck between close teeth.
The sound level is minimal, a fraction of the sound level my adult water flosser makes. It doesnt shake/vibrate too badly in the hand and theyre bith comfortable to hold, and size appropriate for my (4yrs) daughters hands.
It comes in a really nice box, packaged perfectly, making this a great gift for your little ones. The colors and theme makes brushing teeth exciting and fun again for your littles :)

Great for kids
Color: Lightgreen
The HUACOCARE Kids Water Flosser and Electric Toothbrush Combo is an absolute game-changer for establishing a solid dental hygiene routine with children. The light green giraffe and monkey design is incredibly charming and immediately turned what used to be a bedtime struggle into a fun activity that my child actually looks forward to. Having both the sonic toothbrush and the water flosser in one compact unit is brilliant, as it saves counter space while ensuring that every part of their mouth gets a professional-level clean. The three gentle flossing modes and two sonic brushing modes are perfectly calibrated for younger, more sensitive gums, providing a thorough clean without any discomfort.
One of the standout features of this set is how braces-friendly it is; the water flosser reaches those tricky spots around wires and brackets that a standard toothbrush simply can't touch. It is clear that a lot of thought went into the ergonomics and the "fun factor," making it a perfect gift that is both practical and engaging. Since we started using this combo, our dentist has noticed a significant improvement in plaque removal and overall gum health. If you are looking for an all-in-one solution to build healthy brushing habits and make dental care feel like less of a chore, this set is worth every penny.

This is what floss is supposed to be!
I usually don't leave reviews, but after one use, I'm super impressed.
**Note: If you have really tight teeth, this product is not going to work for you and will probably shred.
Using traditional floss never really felt like it cleaned well as it was so slick and wasn't good at cleaning the wider gaps. I tried using those plastic rubber-coated picks for the wider areas, but they were so flimsy and would break or couldn't fit.
This floss is the perfect in-between! It's thick enough to actually clean out the wider gaps, but not too thick that it can't fit between my slightly tighter teeth. A bonus is that it has a bit of grip so that it will actually clean the side of the tooth. The black color is super helpful to see what it pulled out and ensure you don't put a used section back in.
I love the case is refillable and the packaging is almost 100% recyclable. The only thing I couldn't recycle was the plastic bag that the floss came in. I also found the instruction page helpful to put the case together and I liked the personalized note in the package.
The only negatives I can think of is the little tabs on the bottom side could be hard to push open if you have arthritis or other limited hand mobility. These tabs open the inner cover for the floss to go inside, so you would only have to deal with them every 12 weeks or so.
The second kinda negative is the scent options are limited. They only offer two on their website. I would really like to see an unscented option. Overall the mint and eucalyptus is really nice, but I usually prefer unscented floss.
I would absolutely recommend this floss for anyone who doesn't have tight teeth!

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.
