Unit worked well on the first use. On 2nd attempt to seal food products the touch screen began to act erratically, jumping in and out of settings on its own. Very soon thereafter the start button ceased to work. Customer support was initially prompt to respond. I submitted a video of the control pad malfunctioning, but have yet to receive any word other than confirmation of receipt of my documentation. It's been a couple of days now and I'm getting a little nervous. I was initially pleased with the construction and performance of the vacuum sealer. The unit is of heavy, durable construction, but that might not mean much if the electronics are garbage. I don't want to jump to that conclusion until i see how well the product is backed up by Vevor. Analog controls might be a more reliable feature, if you're in the market. I'm hoping to be able to follow up with a positive post script to this review.
