Anova Culinary Precision Vacuum Sealer Pro

The sealer was finicky from the start. After using about once a week for a couple of months it would vacuum, then seal, and within a minute the seal would leak. We called Anova customer line, was directed to leave a recording for a call back. It took 3 days to get a call back which directed us to an online form. I believe a replacement heat bar would have fixed the problem, however Anova does not repair items or supply parts, your only option is replacement. We provided all the information requested, and then received an email requesting the information we had provided and a video of the unit not working. Provided that and were sent a shipping label, requiring us to send the item in before it would be replaced. After 3 days they closed our claim because they had not received verification of shipment. I have left 3 additional voicemails, which they only reply to with additional emails. I had requested a refund on return, due to the time and needing a functioning vacuum sealer. They have denied us a refund claiming we are ineligible because we purchased from a 3rd party (it was the Anova store on Amazon) I will never purchase ANY Anova product again and will ensure all my foodie friends are aware of the company's issues.
