When we first installed it, there was a very strong methane smell from the dispensed water. Now, after dumping the initial gallon or so of water on a daily basis...there is hardly any smell in the water at all. I had previously purchased the filters twice before and this was the first time I had any issues with the filter/

I think it was missing the brackets that holds sides apart at correct distance, (this one was used).  We had to modify the installation, but once installed it works fine. I also bought a new one, it had all four side on the bottom frame, made installation much easier.

At first I was worried that it wasn't working, but now it is working great.

A little confusing at first, but once we got the hang of it, it works like how we thought it would.

Initially we were dissapointed. We had to do a little repair when we got it.  But that worked out fine & now we are happy with it.  There is only a little surface area that holds the mechanism to the bottom underside of the cat.  It was falling out & we had to hot glue it in place, in order for the Cat to work.

This product is great when you first install it.  After a year of droppings from Maple and Evergreen trees all the openings get clogged.  I pulled out a couple and cleaned them this spring and got on the roof and blew the rest off with a powerful leaf blower.  Now in July with a steady rain the water runs off the product before it can go through it.  Actually leaks into the overhang and the water runs out the overhang vents.  It's got to be causing sever water damage.  Going to pull them all out and put them in the trash before more damage is caused.

while starting it up for the first time, there were software issues. I had to restore it to factory settings.

Quite difficult to install, but once in place is a good product.

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

we had to do some cutting at the edges to make it work for us.  Not really tested design for the system as we could tell.

it was easy to install but I had to make some adjustments in order for it to fully work.

The first day of installation I smelt GAS! The installer had to replace the controller before the unit was running. But then, later that night the garage filled with gas. Its a good thing my wife went out to the garage or the house would have blown up. It turns out that when the water heater was manufactured that a screw went right through the pilot gas tube. We were amazed that the pilot light even lit! We were lucky we were not killed because of the gas leak from the shotty manufacturing of this unit. I now believe the other reviews.

When I first tried this in my car, I was excited to find it working fine. After the first use though, it stopped. I opened the device and had to bend a piece back into place to get it working again. (It's working now; well see how long)

We used this quite a bit so it didn't hold up well. But it did work well when we used it.

It was hard to assemble at first but we got it working and it works great!

The problem was with another component but we installed this anyway and it is working fine.

In the end this works. However, the instructions for installation may have been more suggestions or even just clues on how to do it. At more than a couple of steps things did not happen as described and this turned into a multi-hour process. In each case where it seemed to hang a restart of the PC helped move it to the next step. I can say that if it gets scary don't be afraid to restart the installation or restart your PC and just follow your nose.
