Review: Good - Good
Review: Nice to carry around - I been using this for a few weeks now and I love it. Way better than carrying my Viavi or Exfo OTDR when I just need to get the levels real quick. The levels seem pretty accurate, It turns on and off fast and I never change the batteries yet. Also good for giving to a new guy when you have alot of levels to get and not have to worry about damaging your good meters or OTDR or forgetting it somewhere lol. Im ording a few more.

### ⭐⭐ Size is great, that’s about it.
*by M***R on 23 November 2024*

For £33 I would say this product is a total rip off. I’m not trying to be mean but it is constructed out of the cheapest plastic you can buy and something you would expect to find from the pound shop. The only selling point is the size, which is really good. You can just tell by the feel that it’s really cheap and will not last that long. Even the batteries don’t fit in nicely and are slightly lopsided. One drop and I reckon that’s it. Compared to the cheap massive meter I was issued at work (much cheaper) it at least has hard plastic and rubber around the sides for protection. The only downsize is the size which is a bit cumbersome when you have to fit in your pocket when climbing a telephone pole. My advice check Ali for something similar and closer to the £10 mark. Edit: After owning this since last year I can honestly say it's not worth money. The buttons are too sensitive and will turn on and deplete your batter if kept in your pocket. The cap protector broke within a couple of weeks and dirt gets into it giving false readings. The only selling point is the size which is negligible when compromising on quality.
