Yes, I have one of the prototypes on the PSP. It works great most of the time. The only real problem I have had with it is sometimes you have to push the reset to get the turn signals to come back on. I'm not sure why and it doesn't do it all the time. It always turns the signal off after you make a turn. I guess if I had to rate it again I would give it a 4 out of 5. :roll:
I have used the Signalminder. It works great. You can suspend the counter by attaching a wire to your brake lights and can turn your rear turn signals into running lights. Adds some visibilty to the rear. I have changed out to all LED's and like other units, the Signaminder works as a load equalizer too.
The one negative is that you do have to manually reset the switch. I have heard there is something Signalminder now recommends for that, but It is not a problem for me.
Get something either way...I think the cancelling signal unit is a Safety issue.
