I've never been one to balk at the cost of good PE gear, but
daaaaaamn ... that's pricey
-- Interested to hear a future report on how it performs.
Yeah I know it's pricey. They were running a special that came with a custom cylinder and a bunch of other shit and I fell for the marketing campaign. Oh well. I've had my eye on it for a while and saved some money with the package. Anyone ever notice when someone says they just saved money that means they probably spent more than they should have just to say they saved?
Jelquing (as the section underneath the grip gets pushed inwards) causes a 3-dimensional deflection/momentary deformation of the various tunica lamina so that it 'breaks down' a little bit and can effect a bit of plasticity as it heals/remodels itself.
Hundreds of these add up their small individual effects into big cumulative effects, as you're seeing. This stuff is what PE is all about .. (but it seems like it's gone out of fashion for many users. Good basics makes for good gains).
Collagen is VERY strong lengthwise and sidewise. Trying to make collagen do what we want it to by pulling it longways, or trying to stretch it sideways, will make for difficult or nonexistent gains. There must be some deformation stressor applied in directions of force that are not 'North/South' or 'East West' where the fibrils are at their strongest.
Jelquing affords that somewhat by making the tissues immediately beneath the moving grip deflect inwards, ie - down, and the remaining tissues deflect a concomitant amount under the increase in pressure by trying to deflect out, ie - 'up'.

SSJ's too. -- Etc.
Clamping can do that also by making the entire tissues try to deflect outward under the increased pressures (largely sideways, ie - 'East West', but
also outwards) .. but imo if you're not feeling a slight 'burning sensation' during declamping then you're not going hard enough to get far with that. You can also 'clamp jelq' somewhat, along with other advanced exercises, but always be careful with advanced exercises. Know your penis and work up to higher intensities. There's entire forums here on this stuff. Any time something sounds crazy, make a thread asking about it before jumping in neck-deep.
^ Pumping would work by a similar means.. vacuum affording an outwards pull (higher internal pressure) in every direction.
Collagen is at its weakest (most remodel-able) when stressed in a
Diagonal manner. The way to accomplish that is as DLD says with Bundled Stretches. Doing both Jelqs and Bundled Stretches as pre-fatigue to additional length and girth exercises .. (and active recovery methods) .. is going to get you the fastest gains.
(For that matter, hitting length by doing pulls at different angles effects the same thing .. diagonal vectors of force.)
Always bears mentioning as well that collagens have been found to decrease their strength/increase their pliability when heated to temperatures between 104 and 115 Fahrenheit. -- 115 though is pretty hot, so looking at temps between 104 and 108 for real world stuff if you use, or want to try, heated warm-ups. They are absolutely
not mandatory, huge gains can be made without doing warm-ups, but the findings are interesting. If I'd known that ... (a physiological explanation and target range) while I was active ... I probably would have added it in.
BTW nice gain!
