I've found that the angled electrical connector pliers in that set are sometimes angled in the wrong direction. The business ends of the pliers are made to interface with the connector release levers in one direction only. The straight pliers can just be flipped over when they need to be, but when the angled pliers are flipped over, the pliers angle reverses which doesn't always work out very well. Other than that, they really do work pretty well if you're careful with them. It's pretty easy with pliers to apply way too much force to an electrical connector and cause damage. Especially when the connectors are getting old and more brittle due to heat cycling. But for 8 bucks, it's a no brainer to buy. I bought the same set maybe 6 months ago and paid about 10 bucks for it. They've been worth that, for sure.
