Bests & Worsts Reviews from Amazon

I purchased the top of the line Instant Pot as it came highly recommended from family. The pot will not consistently pressurize. So I reset, check everything, (including liquid level) and it fails to pressurize. So I reset, check everything again and retry. Pretty soon, a 1 hour meal has consumed 4 and 5 hours and it's still not done because the Instant Pot will not pressurize to finish the meal. I have tried two meals, and both failed and had to throw them out (pot roast, and a corned beef). So I opened a ticket on March 4th and received a reply stating longer than normal wait times. It's now March 13th and my return window through Amazon just closed. So now I'm stuck with a product that doesn't work from a company that doesn't respond. Do not waste your money or time.
