I find it to be very accurate for heat and to have an even heat through the chamber. The only problem I had was during the pandemic, a part went and I had to wait a couple of months to get a replacement but that has been common with other products.
I bought one in March 2021. Temp sensor failed. Called customer service, they said new part will arrive by end of week. It's been 10 days and counting and no part yet. Customer service is really bad. Going to sell mine as soon as I get my new part. When grill was working, it was great. Just pray you don't have to call them to fix it.
