Review on WYNNsky Universal Tire Repair Kit: Fix Flat and Punctured Tires with 60 Pcs Heavy Duty Tubeless Tools for Motorcycle, ATV, Jeep, Truck, and Tractor by Sameer Hilton

This product appears to be very strong and durable. I've already repaired two flat tires without any problems. My biggest concern before buying is if the grips are hollow to make some modifications to get more leverage when I push and maneuver them. The knife and pliers connected together are very convenient to use. I like the pincer grip when pulling out a nail stuck in a tire. I would like to buy these pliers separately if possible.
