Review on 🔧 Boost Tire Maintenance with Continental Conti Valve Extender: Pack of 2 by Chris Hart

At first I just tried putting one of these puppies on the tire presta valve on the aero wheel but it didn't work at all. As I was preparing to give this seemingly pathetic product a one star and nasty rating, I happened to look at the INSTRUCTIONS and realized that the valve had to be disassembled BEFORE attaching the extension and that the black plastic part in the packaging was a wrench designed to do just that and not, as I initially understood, a cockroach clip lost by a Continental or Revain employee. This is a great product that works great even though the wrench looks like it's part of a drug accessory.
