IR-cams like these have a much better price-to-performance ratio than some FLIR handhelds. Not considering anything else but the resolution (so you may want to take closer comparison yourself), the cheapest gun-style-with-sceen 160×120 FLIR is 500 bucks and the cheapest 160×120 in the same dongle format is still 300 bucks. 160×120 is not even that bad. A 320x240 P1 costs 143 bucks on Ali, but there are also 256x192 dongle ones for 200 bucks (with a temp range of -20°C~+50°C, but 50 Hz instead, I guess, but also there are things like thermal sensitivity (NETD)), so obviously, resolution is not everything, so again, you may want to-do a lil deep dive into this topic, videos on the big video site explain the characteristics and what metters.
