Review on Convenient and Versatile 20-Piece WYNNsky Air Hose Fittings Kit with Storage Case, Blow Gun, Tire Gauge - Perfect for Air Compressor Connection and More! by John Kennedy

The only part I really needed, the clutch, leaks so bad it's unusable. As soon as I put it on. It never worked. Very bad quality. I had to run to the local store and pay more for a muff than for the whole set because I needed it and couldn't wait for the other stores to open the next day. Air is escaping from the part you move to insert/remove the hose end. Not from the connection point, I checked with soap (plus the leak was as strong as compressed air).
