## Customer Reviews

### ⭐⭐⭐⭐⭐ A must have.
*by M***L on February 21, 2015*

If you have any security camera that you ever have to touch you need this device. I love that it has enough power to run itself and the camera (even a PTZ) so when you go up on that ladder you don't have to come back down, and when you do come down you know you don't have to go back up! You can mount and test the camera with all functions as well as focus on the spot...beats going up and down the ladder trying to make adjustments. I see them at all different prices, this was the lowest price I could find...and trust me...they are all the same just packaged a little different.

### ⭐⭐⭐⭐⭐ I Highly recommend this CCTV hand held monitor
*by D***N on October 11, 2015*

Excellent product and great service. I got it quick and it works great! I love it. The case is really nice and it comes with everything I need to make my job easier. It has a rubberized cover which is great and all of the cables and testing tools too.

### ⭐⭐⭐⭐ Worthy Little Tester!
*by C***. on December 17, 2015*

Bought this a few months ago, has a cat 5 tester and the monitor is a decent size. Works great, price was right and I'll buy a few more for my techs. Only gripe is the rj45 port is covered by the strap so it makes it annoying to check cables but the fact it can do it is awesome now my guys have no excuse why cables aren't termed right. Oh yeah and the fact it's a nice screen size, and it has ptz controls for testing and configuring make this a nice little unit that does alot for a little. Wish the display was brighter a few times it was hard to see in full sunlight.
