If you are set on buying an ADS, I strongly recommend this one. Most ADS are primarily for length, so if you want girth you’ll need to include something in your routine (maybe as short as 20 minute routine just for girth). You may have already seen my post, but here is the set up I found to be better than the SizeGenetics and the PhallosanForte.
Posted before: “The starter kit comes with 2 thick sleeves (silicone I believe and you choose the flexibility), a stealth cap, anti-fluid tape, and a universal harness ($49 plus shipping for US).
How I use it is I cut 3 inches (7.6 cm) off one of the sleeves, roll it onto the stealth cap then onto my member. Then I hook that to the harness and hang it around my neck or head and arm. It holds extremely well, basically no slippage, and has a vacuum effect without any vacuum suction pumping parts, as the Phallosan Forte needs. Also, you can change it simply and modify it.”
ErnieBanks uses it as well, but with a knee brace and rubber bands.
I would just experiment with it until you find what works. Remember to take breaks for circulation and to make sure there is no fluid build up.
Good luck
