I have been using something similar for about four years now and love them. My set was made by Mac’s and came with four straps, two of them ratcheting. I leave two at a set length, pull the Jeep forward and attach them, then pull the Jeep back until they are tight and the front sucks down a bit, through it in park and set the e-brake. I then ratchet the back down with the other straps around the axle. It is quick and easy.
I also check mine at every stop and would do that regardless of what I was securing the Jeep with. I have not had issues with the straps becoming loose.
