Stop in for a cup of coffee

Speaking of lights, my local Snappy dealer is running a sale on the under hood lights. The ones that extend and clamp to the sides of the hood. Do any of you guys use them? Do you like them? I have a couple magnetic lights that I just attach to underside of the hood and they work great. The only real advantage I see to the Snap On version vs others is that it uses same battery I already have a million of? Not sure it is worth the cash.
I have 3 I think. I like them.
