TL;DR: Better than every other wireless meat probe in the market.
A few months ago I decided I wanted a wireless meat thermometer after getting sick of dealing with wired probes. Looking at all available offerings, combustion.inc came out as clear winners in nearly all aspects. The owner, Chris Young, posts actively on their subreddit as do many staff members engaging with feedback and issues promptly, and he also has a great cooking science channel on Youtube where he's not over the top about selling his own products.
The site is clear and lists all features, capabilities and limitations so I won't bother copying them all here. The big question I anticipate people having is the 300c limit vs the 550c of the Meater 2+ - the chief engineer explained in a reddit comment that essentially, one flare up is extremely unlikely to kill the probe - so it isn't a big deal unless you intend to use the probe for super high heat searing, in which case you probably don't need the probe anyway.
