About This
- Specifically Designed Refractometer For Saltwater Aquarium --- The algorithm is made specifically for testing seawater and saltwater. This is different from a standard refractometer which is not calibrated to check salinity of aquarium water and will give an error in your readings.
- Automatic Temperature Calibration --- The calibration process should be carried out with both the room and the instrument at 68° F. The refractive index of a liquid changes with temperature. Due to the automatic temperature calibration, any changes in ambient temperature from 50° F- 86° F will not affect the accuracy of the reading.
- Easy And Clear Reading For Saltwater Aquariums And Reef Tanks --- The refractometer comes with a focus adjustment on the eyepiece, this will give you clarity of the optics and a sharp line for easy reading.
- Comes In A Solid Case Includes Pipette And Calibration Tool --- This refractometer is not only built extremely well, but it comes with a durable hard case for easy storage of the refractometer when not in use. It also includes a calibration tool and a pipette.
- Keep Your Fish And Plant Life In Optimal Well-being --- Pure saltwater is crucial for the vitality of your marine or reef aquarium. Use this refractometer to measure the salinity of the water, the target level of salinity in a reef tank should be 35 ppt.

Great product!
Size: Standard--white, Size: Standard--white
Very sturdy and great value for money! Speakers fit perfectly. You can adjust the width and tighten around the sides of the speaker so they’re not loose on the platform. Offers proper stability for the speakers, they will not fall out of the wall if they’re installed correctly and not overloaded with weight. I have the Edifier R1280T speakers mounted and they’re roughly 10-12 pounds each.
**My only complaint which was not a big deal to me** As other people have mentioned, the white plate that hides the screws on the wall is not attached to anything. It was just hanging there loose with a gap between it and the wall, but I got these clear double-sided tape circles to adhere them to the wall and it worked !!! Very quick and easy solution. Maybe the seller could include a few clear stickies in the package moving forward?

Ideal speaker wall mounts
Size: Standard--black
These speaker mounts were better than expected for the price. The mounts hold the speakers securely also tilt and swivel to get the sound where needed. Well thought out design, easy to mount, looks great also. Mounting hardware was included. I would purchase again.

Almost perfect, absolutely fit for purpose, and a great value
Size: Standard--black
These are really, really close to being five stars, but because of my OCD tendencies when it comes to things being true and level, I can only go four. The way these mounts are made, speakers rest inside and on the inner surface of the L-shaped adjustable side brackets, and not on the large metal plate between them. Leveling on the fore-and-aft plane can easily be handled via the adjustment nut on the bottom of the bracket. But there is no provision for side-to-side leveling, so if the manufacturing of the side brackets is not within tolerance, you'll wind up with a speaker that's ever-so-slightly wonky...which is the case with ONE of my mounts. The bubble is still between the lines, but it's kissing the left line. Most would not care about this, and I'm not too bummed about it, but I am able to see that much out-of-true with the naked eye. It's not enough to pursue any kind of remediation, because the value on these really is awfully good. They are solidly built, easy to install, and easy to adjust. The manufacturer is apparently improving the product as they go based on feedback, as some issues that have vexed other owners have not been a problem for me, such as the wall plates being or coming loose (the design now ensures they stay put once pushed back to the wall), or the adjustment nut and bolt rotating freely and not staying tight (the ones on mine are great and function as intended). For the price, these are really hard to beat, and I have a feeling all the mounts like this with the different oddly-named brands are made in the same factory. That being the case, get the cheapest ones, and the day I bought mine, these were those.

Solid and easy to install
Size: Standard--black
These are nice, solid wall mounts. They assembled quickly and easily, and they can hold larger bookshelf speakers like my Cambridge Soundworks M60s. Adjusting the plate to match speaker size is pretty easy, and they seem to grip the speaker tight enough that they won't fall off. The tilt option is very useful and a good feature when speakers are mounted high and need to tilt down toward the listener. Just remember to tighten the bolt on the bottom once you've positioned it where you want it. I would definitely recommend these to anyone looking for solid, well priced speaker mounts.
