I used my Cajun Marinade Injector a total of maybe a dozen times and it really did do a great job.... until I went to use it the other day only to have marinade squirt all over through a crack in the plastic cylinder. Disappointing to say the least. I gave it two stars because before it broke, it worked great. Having read multiple reviews citing the same problem, I know now that the cylinder failure I experienced is a common problem with this model. I was happy enough with the injector performance that I'll consider spending the extra $10 to get the model with a metal cylinder.
