I have noticed i last very long using the keon vs manually even using an intense script. Like 1hr plus. I thought it was DGS initially but i tried manually another day and i lasted a normal time(8-15 min)
I assume it’s because my body knows the movement is not natural but just wanted to know everyone else’s experience.
Scripts have up- and downsides compared to using your hand.
Using your hand and with the likely goal to cum, you hit just the right speed, timing, angle etc. So it works pretty well since you know what works.
With scripts and automated toys there´s 2 things that can happen. Either it´s superintense, surprising yourself with a pattern and making it feel better than you could do with yourself moving it. Or it´s just off enough to turn it into a tease.
There are definitely scripts that are really intense but don´t build up or simply don´t push you over the edge, being able to go hours if needed. Just keeping you at a nice level without finishing it.
I learned that this is a lot a choice of the sleeve. Some just don´t work well with fast or intense scripts while others don´t work well with automated toys in general.My go to fleshlight isn´t even a superwild or tight one, but in an automated toy it´s really intense.
I would try around a bit to see which sleeve works better with what style of script, wild creative ones, monotone ones like a fucking scene etc.
I can tell you that while some wild creative ones feel really intense and good, in many cases pretty monotonous fuckingscenes with a relatively even rythm work best for cumming.
What I did in such cases where I don´t seem to be able to finish I built myself a little finisher-folder. Scripts that work well for me and are reliable at finishing the job quickly, and many have this repeating rythm that´s not too fast.
On top, and something a lot of people mention on a regular basis and I can agree to, too, is that some scripts are too intense and making you numb. You don´t even feel it that much, but once you return to a pattern that was really intense before but now it´s not shows this numbness.
Repeating myself here, but just experiment a bit with different styles of scripts, maybe you just didn´t hit the type yet that works best for you. Hope this helps at least a bit 
Thanks for the insight, the sleeve does make a difference, i have noticed this as well. I will try different creators and see what works well.
its the sleeve…its cheap and not very ribbed or tight. switch it with various other fleshlights and you’ll see the difference.
I last a lot longer as with keon compared to my other toys. Much short strokes, that’s why I mainly use it to test scripts. 8-15m of manual simulation seem a long time to me. The hand is the ultimate finisher, 5mins top surely lol. Maybe you just need a break for a while or update your toy/content your consuming. A two week abstinence always sorts me out when the toys start to get a bit dull.
