Uptone is great company, Alex great communicator and John great designer. Uptone supports their products, as stated previously, many LPS 1.2 sold, bound to be some failures, and amperage produced relatively low, means its going to run hotter vs higher amperage producing lps, heat is enemy of longevity.
Last spoke to Alex perhaps a month ago, only product going out door at present JS-2, parts shortages impacting present products and some new ones coming along.
