In terms of lifespan It may not be a product for intensive use, for a pro who will use the 24 // 24 but to test all the cabling of my house (and there are quite a few: -)) this will be perfect. Auto mode works smoothly, it tests all 4 pairs over the shield!
RAS therefore, comes with small rjj45 or BNC adapters .... for the price, really great and indispensable to wire a small local network
