Works as advertised.

I started using this addon after Gasnow's stopped working. I like it and it is quite accurate, the only problem is that many times it doesn't update the gas value fast enough in the toolbar icon and you have to click it manually to see the updated value. If that problem is sorted out, it's a 5 stars.

It updates really slowly compared to other extensions. Sometimes it does not update at all. Gas already rose to 1000+ in other gas estimators while this addon still showed 129 (only rising to 500 a few minutes later). Kinda suspicious as well with how I can't find the source code anywhere.
