Electrician's assistant here. As someone new to the profession, I got this set as well as the pliers/cutters with the intention of breaking/destroying, mistreating them to see how much they can withstand. Now I'm looking to replace them after about a year. I've cut nails and screws and large shielded cables (with both) and I've short-circuited them. I've hammered with the pliers instead of a hammer. I've used the flat screwdriver instead of a Phillips. I've filled them with dirt, putty, etc. and with a little oil they were fine. The tester looks really cool and within a week someone snatched it. In short, so as not to tire you, they are definitely worth their money. The pliers are a bit unwieldy but you get used to them. For household/amateur use they are 100% fine, you don't need anything else. For professional use, they're not suitable, guys. Unless you want to change tools every 8 months.

Very good range of screwdrivers! It has nothing to envy to much more expensive ones from other companies! Sturdy construction. I think the price is unbeatable.
