There are no springs to wear out on this shifter, it just uses magnets that hold together tightly and when you move the stick you overcome that force and it gives a satisfying click. Even the Thrustmaster unit which seems nice doesn't have as much tension as this one and has a cheap plastic handle that can't be changed easily. There aren't a ton of sequential shifters like this on the market that I've seen. There are just 2 controls on this unit, and I've programmed much more complicated boards for my motion actuators, wind sim, and other switches I have on a panel that I use with iRacing and other sims. If the board ever fails, it would be very easy to program a new one. The USB cable seems to be not removable but if it does break or get damaged, it is just a standard micro USB cable that can be changed out if you open the box and unplug it from the arduino board. That, along with how easy it is to connect and use. I didn't see any way to adjust the tension but I like it the way it is, it feels solid and in my opinion is why I am giving it such a high rating. You need a fairly solid desk with this shifter because it does require a good amount of force to shift forward and back. I did test out the desk clamp since most people probably won't be installing this in a sim rig like I have and it comes with a thick and a thinner cushion to prevent scratching on a desk. They aren't expensive and any shifter with universal fit adapters will fit. The shift knob is just cheap plastic and works fine but I installed a higher quality aluminum shifter and it feels even better. The entire enclosure is aluminum and has a very solid feel.
I am using this along with Heusinkveld pedals, Fanatec H pattern shifter, a SimXperience direct drive wheelbase, wind sim, 4 actuators, active seatbelt tensioner and 5 bass shakers so there is a lot going on and it was no problem to add one more USB device and set it up to use with all my sims.
It's easy to set up with any sim after Windows detects it as a controller. The electronics used are just an Arduino board, common for accessories like this. The best thing about it is how much force it requires to shift, similar to a real sequential gearbox feels.
If you don't use the desk mounting bracket, the holes line up perfectly in the 80mm channels, but you can also mount it with M6 bolts and T slot connectors to a single channel and it is very solid.
I have this mounted on my 80/20 aluminum extrusion full motion sim frame next to my H pattern shifter and handbrake.
