Comments on Leviathan & Scylla by JeffTron for Android
★★★★★D E· Aug 5, 2024
Works well, great on the fly tuning. Unless ive overlooked it somewhere, I wish it had mag prime. Edit: per developer response I now have mag prime activated! Thanks!

Ok, the app is good, the products are mediocre, the mini microswitches are extra sensitive and breake really fast, 4 stars bcuz does not require an upgrade like the gate titan, and has fast trigger response 1 star I would give for the microswitches that can break at any moment.
★★★★★Brian Alton· Nov 8, 2021
Love the app I have 2 replicas that have this brand mosfet and the app is very helpful for teching and troubleshooting without taking stuff apart. 10/10
★★★★★Miika Pärssinen· Jun 19, 2024
On the fly Bluetooth adjustments make for a hassle-free tuning
★★☆☆☆Johan Ponce· Nov 9, 2025
I updated my phone before installing, so I'm not sure if it has to do with the latest version of Android on my Pixel 9, however it could not connect to my phone even after clearing my Bluetooth cache. It connected just fine on a Samsung Tablet.

Garbage mosfet and app. I did not like. Cannot pull a m160 without precooking on a dsg, and "overcurrent" protection triggers too easily. Get a Perun or a Titan instead.

Terrible... Worst MOS FET!!! The new update is still failing BOOTLOADER
