What's the point of showing a deal if it can't be had?
Mine is still in good order and used a couple of times a week minimum for at least the past 18 months!
I'm sure its a good machine, but I doubt it has the community or depth of support that the Instant Pot has. There is a very active Facebook group, and the UK importers are constantly on there, offering help, advice, spare parts and sometimes even free replacements when people have accidentally damaged something. I certainly wouldn't buy a Tefal or anything else over an IP just because it's supposedly a "known brand".
A possible useful tip from reviewer Sandy Toes: Side note - I cooked 3 pounds of sliced russets for mashed potatoes a couple of nights ago using my 'savory food' ring and the ring emerged completely odor free while imparting no off odors to the potatoes. Who knew that potatoes were an odor remover? https://www.hotukdeals.com/deals/instant-pot-duo-v2-8l-electric-pressure-cooker-79-95-amazon-prime-2737842
Tefal uses non stick and flakes which isn't good long term for durability or your health.
