Tbh i just think those sensors are next to snakeoil 😂 Given how cheap the real probes are, it's not worth the potential headache and anoyance any of the knocnoffs can make.
Some are hampered by steep fees and taxes when importing stuff, clones are usually declared incorrectly and/or below a duty free limit - I think that makes a bigger difference than $15 clone vs $50 real probe, the latter could easily be closer to $100 by the time it is delivered to me.
But thanks to your comment, I checked out their site and found their Ali Express store had a sale, $35 shipped, below the free import limit - yay!.
