I am not voting because i don't think it is fair to vote for innovate because I have never tried the others. I have had a lc1 3 plus years of great service and a lm1 that just died on me although going through the manual lead me to a possible cause for the failure. (leaving it pluggrd to the lighter during startup.) Innovate products will get the job done. I have built a serial cable for a lm1 so I'll most likely go that route again.
