I have been using V1 for about 5 to 6 yrs, change new V1 every 2 yrs, the arrows and laser are the best but too annoying.
Last year I bought a 9500i, tried out for about 10 months (sold it), scare me out because no laser alert, but V1 did (mount side by side of rear view mirror at all time).
I just have new born, so V1 can not use due to noisy.
Any suggestion are welcome,
Have a nice day.
