So as the title says, I recently bought the SS2 and within 24 hours the piston no longer moved, creating suction-release. This is frustrating because it’s not like it’s the cheapest device. I love this forum but that left a nasty taste in my mouth (pause) and idk if I want to purchase anything else from MOS due to quality of product/customer service. These are just my thoughts. I have emailed the sales team here and awaiting a response. This sucks but it won’t stop anything maybe just my trust in MoS products smh.
