Very straight-forward installation. Look to be well made.
I've used this for 1-year now on my K1300s.
If you want to ride your bike more than 1-hour at a time, you will need something like this. It allows you to take pressure off of your wrists and get some blood flowing to your hand.
Like all throttle-locks, it simply makes your throttle difficult (though not impossible) to move. Good for long straights, not for use in any traffic, curves and so forth.
I'm glad I bought these...it allows me to enjoy the bike much more.
