Unity tactical hot button products quality control - Unity Tactical MLOK Hot Button

I have purchased and used Unity Tactical Hot Button switches for several years. Although I do tend to shoot a lot more than most of the folks I know, the quality of the product has severely fallen off in the last 2 years. I have experienced out of the box issues with 2 of the last 3 I received in the last 18 months. All of the issues seem to be related to the electrical components internal to the switches. Also, none of the Hot buttons come with a 9" lead any longer. 7" is too short to attach to a 600DF unless mounted on a longer fore stock. The base product is built solidly, the reason for not giving it 1 star. However, the failure rate is too high for the price charged, hoping another option becomes available as I will not be using this one any more.
