Endust For Electronics Duster (10oz; With Bitterant No. 152), 6 Pack

I ordered 2 2pks. 2 of the cans worked perfect, as usual. But, both of the cans in the other 2pk were missing the tube that connects the trigger part to inside the can to bring the compressed air out of the nozzle. Somebody at the factory goofed in the assembly somewhere. Now I will have to spend postage boxing up the defective products and sending them back. Might try taking them to the WALMART store near me and see if they can at least give me a refund. I've been getting these compressed air cans from WALMART for years. This is the first time I've had a defective one. It is still the best compressed air brand on the market. JJBinPhx,AZ.
