Installed the day we received it.  First off, digital display of numbers were broken/ would not display correctly based upon FM tune.  Also when powered down, did not save the saved preset AM/FM stations.  Returned product.

Ordered it a 10pm and received it the next day before noon. With that being said, I was too excited to wait to install. Took me around 3hrs on my 2005 Ford F-150. The kit has solid directions if you know a little about electrical, I took my install a bit further than whats included in this kit but everything went well. The included connectors and other hardware are not exactly up to electrical spec so I ended up using my own. My one and only complaint is the air line fitting on the horn. I had to redo it twice due to a small leak, not sure what the actual issue was but when I cleaned the threads on the fitting and tightened it back down for the second time it worked and it hasn't lost air yet. If you follow directions the compressor will start and run when you key the ignition, although I am a fan of this, I took mine a step further and added a toggle switch since I mounted my compressor under the back seat. I must say, even with the compressor installed inside the cab it really doesn't make much noise, I can obviously hear it but it won't hinder a phone call or a conversation in the cab if anyone was curios about the noise factor.

The Horn: This thing is F'in loud, I'm talking wake up a neighborhood loud. I gave it one test blow in my driveway and there wasn't a dog, bird, or any other living creature that didn't flinch, run or fly off including me. If its not par with a train horn its insanely close, take my word for it.

Will add photos of install shortly.

So my first impression wasn't a really good one. Got it in and the same day installed it. Defective it was stuck in some kind of loop. Had to return it. I have installed 2 of my neighbors which lead me to buy it also. Just my luck i don't think it was mesnt for me to buy just yet

Received this yesterday and installed it yesterday. Only giving 4 stars due to when installing had to bend the part with the square bolt hole to get it to fit. I did not have enough room to get the bolt holes lined up on the passenger side. So bent the ear a little and the holes lined up and when I tightened everything down the ear pull it self back into the correct position. You will need helper to lift the hitch into place but other than that one person can do the rest of the install. Use W-D40 on the insulators and they slide off to drop the exhaust.

The disposal arrived a day earlier than estimated (always a good thing).  We read the installation instructions and figured we wouldn't have any problems installing the unit.  It took us a couple of hours longer than we thought it would but it was mostly due to not fully understanding how to seat the cushion mount.  Once we realized we didn't have it in the correct position the mount ring worked like charm (this is an EZ Mount disposal not a 3-bolt mount).  The only complaint I have about the instructions are they don't explain how to remove the already installed plug-in cord so that you can use existing direct house wiring.  Wound up just cutting the rubber gasket and cord, removing them and then installing the existing wiring.  Once we got all the drain connections fitted and tested for leaks we turned on the disposal.  This disposal is a 1/2 HP unit and replaced a WhirlAway 191 1/3 HP unit (also sold by Anaheim).  This unit is much quieter.  Don't know if it will last as long as our WhirlAway did (15 years) but I suspect it will based on others comments. And if it dies within the next 5 years Anaheim will replace it under the warranty. I do wish there was somebody in customer service available on the weekend - lots of DIY folks only have the weekend for projects like this.

Initial impressions are good. I just got it installed, and it looks/feels great.

Plug and play. Just installed yesterday in my front window. Took less than 2 mins to put the parts together and mount. I'll let you know how long it lasts.

I had some trouble installing it (it spilled some water first).

On a related note, I wish the review request was not so prompt after the purchase. That way, the evaluation would include some operating experience, not only the installation experience.

Direct bolt on replacement, took five minutes (if that) to install.

My unit was installed last week.  It took 3 days to install and troubleshoot, including pouring a concrete pad and running cable under my house.  Admittedly, my contractor had never worked with this unit.  Still it seems like it should have been easier.  My dad also bought one and it took his installer (a dealer) a day and the site was much easier.

My biggest gripe is that this thing is LOUD.  My neighbor has already complained.  If you buy this, make sure you put it in the place least likely to annoy the neighbors.  Also note that this runs every week for 12 minutes to test itself.  That's 52 opportunities to annoy your neighbor(s) - and possibly yourself.  You can set the run time, but don't make the mistake my contractor did.  He entered 3:00 as the time (as an example) when he should have entered 15:00.  So it was 12 hours off and did it's test at 3:30 in the morning.  That's when the neighbor complained.  I don't blame them.  I would have complained too.

This puppy is basically a motorcycle engine in a box.  I don't know why Generac can't muffle it better.  As I note in the title of this review:  I hope it works well.  Installation and tweaking was hard.

Installed the unit with no trouble at all. Removing the old one was quite hellish, but this one was fairly straight forward to install. I did need to buy some different plastic pipe to make it work in my set up. The unit is both quieter and more powerful than the one it replaced. I'm happy with it so far.

Installed it yesterday 19/7. Kinda early to rate. Ask me again in about 6 weeks or so.

It was easy to install. My husband and I were able to do it in half a day (I didn't keep track of the hours). It is quiet, which is great since our bedroom is right over the garage. Nice features that we love (keypad, security). Great value.

It was installed as per instruction and to a T. It worked for an hour or so, then quit completely. Any additional effort failed to get it going. Item was returned for credit.

I bought this based on some positive reviews...obviously I was disappointed. Good luck.

Installed the first one, and so far, it is working fine. Only have had it for a few days though, will need to see how it lasts.
