Overview

This Holybro SiK Telemetry Radio is a small, light, and inexpensive open-source radio platform that typically allows ranges of better than 300m “out of the box” (the range can be extended to several kilometres with the use of a patch antenna on the ground).

The radios can be either 915 MHz or 433 MHz, and you should purchase the model that is appropriate for your country/region.

Excellent product for dry mouth
Scent Name: Berry, Size: 100 Count
If you are having trouble with dry mouth, especially while sleeping, this is definitely the product for you. I have severe dry mouth and have tried multiple things including hard candy (yes, I know not very smart) as well as different biotin products, the mouthwash, the spray and the gel, which all do work, but do not last for very long. These stay in place open the corner of your mouth, last for hours and truly work. I highly recommend it if you are having a dry mouth issue

Works great
Scent Name: Berry, Size: 100 Count
I have to use these for about 1/2 a year. I keep bronchitis and sinusitis from about Oct. to April every since I was a child. When I am suffering with these I can't breath through my nose, epically at night while sleeping and would wake up several times a night with dry mouth so bad ir was literally painful. My mom turned me on to these because she was using the with her CPAP. I sometimes have a bit of difficulty getting them to stay put but overall they are great. I have tried the OG, cinnamon, and berry. The OG have no real taste, but you wake up with a sweet taste in your mouth. I tried the cinnamon because I love cinnamon and didn't listen to the reviews stating how strong the flavor is, big regret, it's like putting two or three fireballs in your mouth, won't be making that mistake again. The berry ones are actually best in my opinion. They have a light berry flavor that isn't overpowering, isn't quite as sweet as the OG. Whichever one you choose you won't wake up in pain. I do suggest using only one at first as opposed to the two they recommend, unless you like waking up with your head on a water logged pillow. One generally gets me through the night unless my congestion is super bad, then I will sometimes have to use a 2nd one about 1/2 way through my night when I wake up for the bathroom and realize it's already completely dissolved.

Happy to have a stainless steel one
I'm a female and I tried a few others, but this one seems to be more comfortable in my mouth. I would've given it five stars, but I wish it had one side, a little bit rougher than the other side. I'm spoiled with the one I had which was plastic, but it was perfect. Otherwise one was a milder scraping than the other side, and I seem to like the more aggressive scraping. People who have never used a tongue scraper will be just fine with this and I'm going to stay with this one. Just have to do it more times.

Solid and dependable product
This product has had a positive impact on my oral health. It is well made of solid stainless steel, and is comfortable to hold and use. I have no doubt this product will continue to work for me for years to come.
