Reviewed in Canada on February 4, 2022
Used it for few hours on home closet, nailed ~100 16 gauge finishing nails 2" with tiny 100psi max. 3 gallon compressor (used 70-90 psi settings). Overall Result = I'm very pleased.

A few nails that didn't go in all the way, I hammered them in (16 gauge). Learnt quickly that increasing psi on the compressor solved.

Yes, it leaves a 1/4" indent which is tiny and totally not even a concern, I hardly even noticed or care. Once I paint the cabinet, it'll all be not noticeable.

Don't know why some are saying 16 Ga nails don't work, because that's all I nailed. Use chart as shown on product for correct use. Ensure you're putting the 16/18 gauge nails on their own side and slide the loader up with a push.

I've only used it on one project so far, will update the review if needed. $65 for 3 tool combo, utilizing unused tiny compressor at home = fantastic deal!
