I purchased a Mark 5 from Gus, and it was a ride lol. I used pay pal originally, and for some reason it got hung up. Not due to funds, not for any reason that my bank or PayPal could give me. So, I went out on a limb and sent him the funds again through Zelle under the understanding that whenever the PayPal funds hit, he’d return them. I suggested it as I felt bad having him wait due to some hang up on my end. Long story short, it took weeks for the PayPal to go through, none of it made sense but he kept communicating and was absolutely diligent on returning the second payment immediately. To say he’s good to go is an understatement!
