If you plan on turning left and right, order two sets.

The photo is deceptive, you don't get two of the same brackets, you get a mixed bag of random parts, with no instructions. If you have two turn signals, you will need two sets of these. or just only turn one way.

This is basically the same review I wrote for the Metric Wrenches. I originally bought a set of these wrenches that were reversible, but to reverse the direction, the wrench had to be taken off of the nut or bolt, flipped over, and then put back onto the nut or bolt head. I like this style with the direction selector built into the tool, so if the direction needs to be changed, it's a simple flip of the lever. These wrenches are good quality tools and should last me a long time.

I need to order some more so I won't have to switch bikes; need more for guest to use also.

Ordered 2 sets. One was fine but the other I got 2 left brackets. Not a huge deal but it makes them look a bit awkward

I had to wear the left one backwards because they sent me two right handed ones instead.  They are kinda small but went very well with my halloween costume.  It would be more worth it to buy gloves at a local store or halloween shop.

I love the ability to just turn them around the other direction

Now I have two in case one gets lost for a while.

Very easy to install. Did left-side first and then did right-side.

Only worked on the left side, didn't want to take a chance on another pair, no problem returning them, no cost to me.

Not good for driving because it keeps you from seeing things to the left, or right, for that matter unless you turn your head. But I still like them!

Works as advertised, but make sure you order the correct open position. Is it to the left or to the right?  I do not pay attention and as a result purchased the wrong one. Low enough price that throwing it away and buying another did not mater.

The one's we received had the green light button on the right not the left as pictured.  Which turns out is exactly what we wanted.  So the picture seems to be mirrored left to right.  Works great though.  If you plan on using several you might want to make a chart of how you set the four dip switches.  When I was testing my handy work I switched the light on and off several times than sat down to rest.  The light then began flashing on and off on its own.  I was confused until my son came upstairs and told me his light was turning on and off.  Only then I realized I set both to the same code accidentally so it was turning on and off both lights.

if you don't need the left button, then this is the best choice.

Ordered with out researching and knowing you need to order the proper side. I have checked and rechecked the item and it does not ask, which side you need. I guess its luck of the draw which side you get. The one I received was for the left, and of course I needed a right.

With both pieces tightened all the way, the right one held great while the left one had some movement. I used the shims provided but just wasn't quite enough. Once I had figured this out I had already installed the set and scratched the bolts so I wouldn't imagine they would accept a return - therefore I live with it. If both attached perfectly I would have given it 5 stars.

These should come in pairs - I had to order another one and it doesn't match the first one I ordered

We ordered 2 sets.  Keeping a set for us and passing  the other set around to the neighborhood kids.
