I enjoy and use your VUSE products. I have the VUSE solo products. The solo cartridge is a good product, the continual problem I am having is with the rechargeable battery products that you are selling. They are inconsistent and unreliable, they have a short product life. I have made several battery purchases from your vendors and a couple directly from you. I know your website states they will last 1 to 3 months, but for $11.99 ea, they should last somewhat longer. But let me just at that I believe your product is a better alternative to cigarettes, there is no tar in this system. Thank you.
