Seems like a decent set. Definitely needed for use with the Klein circuit finder. Only reason I gave it four stars was because I think at $15 they’re priced a bit high (the bulb socket and 2 prong to 3 prong plug are very inexpensive to purchase separately). The alligator clips are necessarily expensive either, but would have required putting something together if not purchased in this set. A $10 price would probably be perfect on these. Other than that the quality seems great and would definitely them.
