I bought my Shoebox Freedom 10 about a month ago when I noticed they dropped the price to $499. I finally got around to using it today. I have to say I am very pleased. I was impressed on how fast it topped my tank off. I bought it thinking it was a "turn it on in the morning and come back at the end of the day" kind of a deal (which I was fine with). I accomplished what I needed in about 2 hours. Here is a rundown from my 68cf Tiger Shark tank at 2500psi:
10:12AM - started F10 with tank at 2500psi
11:15AM - tank at 3500psi
11:48AM - tank at 4000psi
12:06PM - F10 shut off at 4300psi
I did not try to adjust the auto shutoff feature to go another 200psi to 4500. Maybe next time but 4300 is fine for me. In the future, now I can fill myself, I will top off my tank when it gets down to around 3000psi. So I should be able to top my tank off in about 1.5 hours based on how it went today.
