About This
- 【SPECIFICATION】The reading is temperature-corrected and accurate to +/-0.001. The unit of specific gravity is 1. 000-1. 030 (ppt value: 0-40 degrees), the safe area is 1.020-1.023 (ppt value: 27-31 degrees), and the low specific gravity area is 1.000-1.019 (ppt value: 0- 26 degrees), the higher specific gravity area is 1.024-1.030 (ppt value: 32-40 degrees)(Note: PPT value indicates salinity in the outer range of the scale)
- 【MATERIAL】The salinity tester is made of transparent acrylic material, which is relatively hard and easy to read the salt and specific gravity of your marine aquarium
- 【 DESIGN 】 The easy-to-read swing arm pointer and ultra-wide stable base provide accurate test results
- 【APPLICATION】The aquarium saltwater hydrometer can perfectly test the salinity and specific gravity of brackish water and marine fish tanks, including the solubility and specific gravity scale. At the same time, it is very suitable for fresh water and sea water
- 【NOTE】Before using the salinity hydrometer tester for the first time, fill it with warm water and wash it with detergent before using it. After use, immerse the salt water meter in weak acid (vinegar) for 30 minutes, rinse with tap water and air dry

Works great, super easy to install
Color: Black
Easy to mount, fits large charger great. Low profile appearance keeps it out of sight, functions perfect for my needs. The thick silicone material is nice and stretchy, thick so it should be durable.

Don’t but this…
Color: Black, Color: Black
The holder came quickly and isn’t that bad but mounts with a huge adhesive backing, which again isn’t;t bad, but it was sent in a plastic bad, like a zip lock bag. The adhesive backing has NO protecvtyive strip on it, so it is covered in lint and debris and was sticking to the bag it was sent in.

I just hope it will last for a long time
Color: Black*2
The material is not cheap, I mean it’s a really good silicone!
Very easy to use out of the box, and it did fit two of my bricks.
All I hope is that it will last for a long time stuck under my desk since I had to stick my bricks upside down.

Works great. Keeps things nice and tidy.
Color: Black, Color: Black
Works great! I regularly use the end of my dining table as a spot to use my laptop and really wanted a more organized way of keeping the cord tidy. This of course would also easily work on a desk as well
It's completely made from a nice stretchy and durable silicone and could accommodate pretty good size chargers. My charger is pretty small so it doesn't fit tightly, but it still works perfectly. It's also super easy to install. The reverse side of this has really strong adhesive to hold onto whatever flat surface you attach it to. Mine is adhered to the underside of a wood table and so far it doesn't appear to have any issues with it. I should mention that since it's held on by adhesive, it's not something you can easily move after installed, so put it where you want it to permanently be. That said, for the price you can easily get a second or a third one if you need it in multiple locations.
Overall, it works great and it really keeps my laptop charger off the floor and everything is nice and tidy.
