Installation much more difficult than expected

These are nice build quality, but more difficult to install than anticipated.

The instructions are a mash-up of German and English. Rather than explaining the process step-by-step, there are just two large paragraphs (front and back assembly) and a unclear few drawings. The assembly pieces come all jumbled together in a few small bags without any identification or description of their use. It's mostly trial and error to see if the included parts are needed.

I had a lot of pieces left over and probably didn't use everything as exactly intended, but it works on my bike and looks nice.

It was unclear to me that the metal supports require cutting, so I assembled with the black clips only to realize that they needed to be removed (and breaking two in the process since they lock in).

The instructions say to use a hacksaw to cut the supports, but that will cause burring on the end of the metal and make it impossible to insert the supports into the clips/receivers. I ended up filing the edges down to a smooth point.

Finally, when installing, the fenders have a tendency to twist depending on the amount of tension created by the supports, so lots and lots of micro-adjusting is necessary to have straight fenders that are also equally spaced around the wheels.

Remember: DO NOT install the black clips until the very end.

Recommended steps to install:
1) First install the supports attached to the fenders and slightly tighten
2) Remove wheels of bicycle
3) Place the fenders into the bicycle and put the wheels back in
4) Adjust the fenders and mark the supports where they need to be cut
5) Remove wheel and fenders
6) Cut and file edges of supports so they are smooth
7) Install fenders
8) Install the wheel
9) Adjust the fenders

Alignment and attaching to the disc is not as simple as instructed.  Be careful!

Seriously difficult to install.  2 person operation with a lot of swearing - you would think for a $100 they would offer a project that included something besides plastic screws that break.  Would NOT buy this again.

I haven't even taken this out for a spin yet, but I will say the installation instructions are awful!  I highly recommend spending 90 seconds with this video before starting the installation, it will save you much more than 90 seconds of aggravation on the other end!  https://www.youtube.com/watch?v=WB9c8yQKX58

NOT easy to install; couldn't adjust the way it hangs on my front door window.  The bracket lines up with the door frame, but the shade is lop sided and can't be modified with the difficult hardware used for its installation.

the idea is great,  but installation was a pain. I ended up trashing the software, and writing to Nuance

Good quality but very difficult to install. Directions are minimal. Not for just the average DIY'er, requires special electrical working tools/wire stripper.

Was more difficult to install than it should have been.  Once I got it on, it seemed to work fine.

It's really hard to install. I read the instructions, watched the video, etc. Still, the installation involves sliding the basket on and off the clips twice (you put one side on, slide it off; then the other side and slide it off for 24 hrs.) It's hard to slide the basket off. It takes some jiggling but that pulls the adhesive off and you need to start all over. The when you are trying to get it back on, the clips are really close so it's hard to align without A) flicking off the side you just put on or B) accidentally touching the side with the open adhesive onto the wall, causing it to stick before its in place. I finally got it sort of on but it seems crooked. I just gave up. The contents are very, very light (~7 oz) so I decided it should hold OK that way,

installation was a bit of a challenge since the tape, required for installation, was tightly stuck to it's lining...  getting the tape loose and usable was the biggest challenge of the installation.

This is near impossible to figure out how to install.  I will give it another try.  Might have to return it.

very difficult to apply; had to purchase another

Easy setup, instructions are not very easy without trial and error.

Extremely difficult to install. Returned one to seller after unable to install.

Works well but much hard to install than instruction indicate. Extra drilling and fog light mods needed.

It was exceptionally difficult to install and when I had it almost done, I realized it was missing pieces. I ended up just returning it and buying a cheaper one which installed super easy and works like a charm.
