I recently had some issues with a faulty MRS on my Dragon BC. I was unable to get any assitance from several of the local dive shops. They were happy to sell me a new one even though mine was only 9 months old. I reached out to Zak through this site and he definetly helped me out. I have been very happy with Mares products over the years and was happy that the relationship will continue thanks to Zak's great customer service! Thanks Zak!!!!:
