Translogic use two types of shifter sensor, one is a pressure sensor, a little resin shrouded 'box' on the link shaft with the cable coming out of it. This is great, and works very well. The other, older, type looks like a mini shock absorber, or a suspension data-logging sensor, and is crap. Fragile and not very water-proof.
The rest of their stuff works OK, but you have to be really careful with the quality of your connections (normal, really...) and I've had a few problems with the software, but other units have worked just fine, and the general consensus seems to be that they do the job.
Happy shifting !!!
