A thorough review of the TopTes Tools PT520A combustible gas leak detector. It seems like decent value for the money and compares well to much higher end and higher priced models.
Buy one here: amazon.com/dp/B0BTM3G8DK (not an affiliate link)
10% off discount code: UXWBILLYT (valid March-June 2023)
There is also a 10% discount "coupon" checkbox available as of this writing on Amazon's US store. Whether you can "stack" it with the discount code I do not know. Tell me if you do and it works!
I believe TopTes is using the Winsen MP-4 gas sensor in both of their detectors.

I would like to see TopTes improve their instructions with a warning about butane temporarily disabling the sensor. I would also like to see them improve the PT520A's display so it is readable in sunlight or bright room lighting. Finally, it would be nice if they'd sell the replacement sensors, so you can renew your leak detector after the sensor wears out.
The TopTes detectors are not designed to detect byproducts of combustion (carbon monoxide, etc.). Be sure you're getting the right product for the job you're doing.
