Overall a 5+ product. Easy to use, robust and equipped with everything you need. Comes with a drill bit, but to my disappointment it's smaller than stabilizer heads that use a 3/4" drill bit. Carrying a head around is a stretch and will generally only do so when I get off the drill. in a drill press. 2? Let's see how fast I lose it. The chocks come with a nice ratchet wrench that works great and those who don't have a cordless drill should have no problem using this product. Can't tell if there's a huge difference in performance to other scissor pads but they seem to hold the tires tight. Overall very satisfied.
