In general, I like them. The "pliers" are small enough to reach smaller lightbulbs, but at the same time can work with some of the larger automotive bulbs. The insulating tips don't hold the bulbs as well as I would like, but with a small number of patients and a few tries, I was able to remove the bulbs coming in and out. Although I didn't break the glass bulbs, enough pressure could be applied with this tool to break a glass automotive lamp.
