At this price, it does the job asked. It takes a little press the "trigger" to properly cut the shield of 2.5mm son, no need to press for the RJ45 or coaxial cable. Less than 2 euros, it's perfect. For 5 euros I would tend to say that we must sharpen it a little more As against a very positive point, when I use an automatic wire stripper and I do not have enough bare a few millimeters, it is virtually impossible to recover the it work perfectly, a ride and it's good. I highly recommend this product.
