Product: 1x Black Motorcycle Cruise Assist Hand Rest Cruise Control Handlebar Universal Fit Grip
Overall sentiment: positive
Customer reviews:
Can be difficult to attach because it's so tight....I soaked it in hot water for a bit to make it more flexible, and that worked.  Maybe there's a better way, but I don't know. I have a standard motorcycle grip. Once on, it's easy to adjust for use.  You certainly can buy a more technological/expensive cruise control, but this thing does exactly what I wanted and is so inexpensive.  Just can't beat it! 
 Love this perfect fit handy unbelievable use for control ty 
 cheaper than the crampbusters. It also has a wider than normal palm rest which takes a little getting used to, but once you it is smooth riding. 
 Helps save on the wrist cramps! 
 Excellent product on the cheap. Works perfectly on my '14 FXDF with the longer rides. I keep it on/use it all the time, actually. Thanks! 
 It works. 
 Best purchase yet.. It really helped with my wrist strain I was having.. 
 This cruise assist is about as simple as you can get. It goes on your throttle grip right about in the position you would be when you reach your cruising speed. Naturally you can go faster or slower while using it since you just press with the bottom pad of your hand. It is molded to fit.
It is best to soak it in HOT water and it will soften up and mold to fit your grip as it cools. It only takes a couple of minutes. You don't have to grip the throttle as tight and when using more of the bottom of your hand to press it sire relieves the tension in your hand during a longer trip.
The thing I like about it is you can regulate your speed easily without turning other types on/off, adjust, etc. it is always in your control. It can use it in fairly tight traffic without worry AND it is molded to my hand so when I hit the twities, gravel or the light off road my old body can take it is just a part of my throttle handle.
It works well for me and you cant beat the price!
You are always in control with no chance of a runaway upon hitting less than ideal traffic and road conditions that come with little to no warning
AND it is quite small, only about 2 1/2 inches at the flair. The photo of the product on a grip is accurate.

 It really helps rest the hand grip on long rides. Shipped fast from the other side of the world. 
 Item works as decribed 
 good.. shipping to long 
 I did not think that this would work but I have been using it now for about a month and since I have a bad wrist this little hand rest work absolutely great. 
 works exactly as intended 
 I HAD THESE THINGS BEFORE AND HAVE WORNNED THEM OUT SO I AM BUYING MORE FOR ALL MY MOTORCYCLES.. I HAVE A SEVERE NECK INJURY THAT CAUSES MY FINGERS AND HANDS TO TINGLE AS IF THEY ARE ASLEEP.. SINCE I LOST MOST OF MY FEELING IN MY HAND I SOMETIMES GRIP THE THROTTLE WAY TOO TIGHT AND GET FATIGUE OR CRAMPS.. NOW I CAN USE MY PALM OF MY HAND TO HOLD THE THROTTLE OPEN WITHOUT GRIPPING IT.. SAVES MY HANDS.. DEFINITELY WOULD RECOMMEND TO ANYONE. 
 good quality works good.
