Installation is easy, but tricky.

This went on a 2011 Wrangler Unlimited.  The instructions are straightforward, and "pretty close" to reality.  However,  You'll need a pair of good, long needle-nosed pliers or hemostats to get the washers and nuts between the frame and the bumper...it's pretty tight.  But...I still got it done within 30 minutes or so.  I have not tackled the wiring harness yet.  More on that later.

performs wonderfully; more difficult to install than anticipated

I found that it was much more difficult to install than anticipated, but once installed, it has worked well so far.

Pretty easy installation, however the electrical connectors wouldnt lock together no matter how hard I tried. I pushed them together, insured operation and zip tied.

Pricey for what it is, but makes installation easy.

A couple of things that make this product a bit more difficult to install.

1)  Mounting the unit can be a challenge.  It comes with a plastic mounting bracket that you can attach to your roof's eaves but you may have to improvise by building additional support structure to make this work.  I had to mount a 2x4 to my eaves to create enough off-set away from the roof for the bracket to attach properly.  I also had to extent the height of the supporting bracket by attaching a short length of 3/4 schedule 40 conduit to raise the sensor above the roof.  Since the sensor attached to a 3/4" pipe I may build a more rigid support using galvanized pipe.

2)  Getting the unit linked with Weather Underground was tedious.  I had to create accounts with both Acurite and Weather Underground sites and then associate my weather station with a Weather Underground assigned identifier.  The Internet bridge that comes with the unit connected flawlessly with the Acurite without any intervention on my part.

Finally got everything to work!  The Internet can now see the weather in my little part of paradise!

Bought this at the Home Depot, not Amazon It's beautiful in appearance. The right styling for our application, but I give it four stars because the installation was a lot more difficult than it needs to be. If your electrical utility box is installed perfectly flush, it will be an easy install, however if the box is below the surface of the ceiling, like most are, and esp if you.ve got an uneven ceiling then the screws become too short and you really have to mess with it. I've done a lot of these things and it definitely CAN be a lot easier. If a threaded pipe/conduit had been used in the middle to thread into the t-brace, like most of these installations do, it would have been simple. 1) Install t-brace with screws. 2) Thread eye ring on to threaded pipe. 3) insert into canopy and screw into t-brace till tight. 4) Done. But instead you have to take it off and put it back on multiple times until you get it spaced/gapped right.....SO, install is definitely NOT a 5 star affair.

Overall the unit works well, once you get it installed. The directions were confusing as there seem to be two different ways to install. Some parts work with one installation and some with the other. Neither was complete. I was able to buy the parts necessary to complete the install.

Kinda a pain to get installed, but works great when it's in

I'm happy with my finished result, but it's definitely NOT as easy to instal (using the provided instructions) as it claimed to be. Be vary that if you want the finished product to look good and be perfectly installed you might be dissatisfied with the end result. I just wanted the added security and it delivered on that.

installation was a royal pain, but once it was done i haven't had an issue with it after a year of use

not the easiest to install, but for the price you can't complain, reccomended for practice before you install anything more expensive

Seems to be a good product, but installation is difficult.  I had issues with getting the guards on each of the motors while trying not to break the motor mounts or anything else.

It worked well for me in my second attempt. The included instructions are not very clear, and that was the reason of my first failed attempt to install it. I suggest you to look additional info and photos of other customers.

instructions for installation were not very helpful and therefore difficult to install.  Had to go by instinct rather than by the printed instructions, but once installed, very happpy with the product.
