as described

I always need back ups and everywhere

I bought 10 and was unable to use 3 of them. Shortly after I started to use them, the thread came out. They were junk. However, the ones that do work, work great. It's not a bad product. Just a flaw in the design. I would buy it again.

I use this with my work, as my personal tool. I work for a company that doesn't like to spend money, but has a lot of fiber connection. I used to work for a data center and know how handy these ae to fix light issues where small dirt particles and interfering with he laser and throwing signals off. It has proven itself that the company is now going to start ordering these for the other network techs .

I was expecting a dual LC/SC. Instead 2 SC came.

This is identical to the other three one-click cleaners I've purchased through Amazon. It will clean MU and LC fibers and ports, though I haven't come across an MU connector in 10 years with which I can test it.You leave the cap on and just pop the top to clean connectors, and you remove the cap to clean ports or patch panels. If the panel is very dense, extend the tip to reach deeper without pinching existing fibers. With the tip retracted, you can see the the spools so you have an indication of how much is remaining.

These fiber optic cleaning tools are handy to have and very easy to use. You punch it into a connector or a cable and it swipes the tip with a fresh cloth, then rotates the cloth to a new fresh section automatically. It doesn't require additional alcohol wipes or other cleaning methods, and can be a quick step in the workflow when you join new links together. It's hard to verify cleanliness, but it isn't a bad habit to have to perform a quick 2s pass on each link to ensure there's no misc dust etc that would interfere or degrade the connection.
