Byrna with bad CO2 and NO help from Byrna customer service
Purchased Byrna with bad CO2 cartridges. Contacted Byrna and was informed no shelf life to cartridges and cannot leak out prior to puncture. I got news for them I have a whole carton of FAILED CO2 cartridges and thought the problem was with the gun. Thankfully it was the CO2 cartridges as the 2nd box works fine. BOY AM I GLAD I DIDN'T NEED TO USE THIS FOR PERSONAL PROTECTION. Great idea HORRIBLE customer service. There needs to be a way to identify full cartridges so you don't install a dead one when you really need it
