This guy is wonderful, and his product is exactly as advertised. You've read about my experience with the other guy - typical for me to try and save a buck and end up spending more in the long run. As a result of the other thing, we now own a heat gun (that the hubby wanted anyway), and spent over $10 in the connectors that I used, and then cut out and had to use to reconnect my brake light.
So two thumbs up for no cut modulators! My only advice is not to get it through ebay - it's $2 cheaper and shipping is $1 cheaper through his site.... ask me how I know
