Would give 5 stars but only got five stem caps not six. Didn't get any extra O-rings either. In fact, you just need to contact the seller, but there was no such opportunity.
Pros
✔ HIGH QUALITY - The valve cover and key fob are made of high quality and lightweight zinc alloy, which is durable, rustproof, anti-rust and anti-oxidant even in extreme weather conditions. What you get: 1 wrench, 5 tire valve dust caps (plus one as a spare)
