Definitely worth the $$. If you plan to be on any stretch of highway, you'll be glad you spent the money. And when riding in the cold, it gives some time to warm hands.
Hi, I just recently used it on a long trip and was actually amazed at how well it worked. To vary my speed, i would occasionally inc/decr my speed by holding the switch up/down for a sec. Really allowed me to enjoy the scenery more. Enjoy!
My Roadglide came with it stock and I use it all the time. Had a couple Ultras with it and loved it since it came out in 89. A friend of mine had it installed on his Electraglide and you could not tell it factory install.
