Yes I would purchase this product again. I usually use 1 can at the beginning of summer and it really helps with the odors from air conditioner.This makes the third year I have used this item. I usually only use 1 can during the year.

This is the second time I have bought a batch of this evaporations cleaner. I have a Honda Fit which is known to be stinky after a while. I don't use the tube provided, I use one with a conical rubber stopper attached which I got from a Toyota evaporations cleaner kit. I plug my drain tube with the stopper, spray in the can contents while shaking to keep it foamy, then I use a pair of locking pliers to clamp the tube, then remove the rubber stopper. After 20-30 minutes I get a bottle to catch the waste fluid, put the tip of the tube in it, then unclamp the pliers and the liquid waste comes out. I usually do this at the beginning of the summer to cut down the stale smell. It seems to help and lasts a few months until I stop using A/C for the summer.

Was very effect and would buy again.

I miss the original! Still close and effective, just a little more messy, drips more and foamy. Does not go far, you get about 1 cars worth! For $15 is a lot! Very similar to the old product, had trouble with spray nozzle, fortunately I had the original one from Einz and I just used that.

I had great results. The plastic tube that is supplied is about 24" and very flexible to work into the vent system. I could see my evaporator core about 18" in behind the dash center vents and the tube kept bending down into the evaporator case and the foam was not hitting the core itself just spraying into the bottom of the evap case. I found I was able to strap the tube to a piece of wire coat hanger with electrical tape and that allowed me to control the end of the tube inside the vent and use it like a wand. I was able to control the tube end inside the vent and spray the evaporator core up and down, side to side, and no more awful smell.

I helped two of my friends with their A/C odor problem. One Lexus IS 250 and another is Benz E350. The Lexus has severe A/C odor problem and this product helps getting rid of it 80-85%. Still beats going to the dealer to disassembling the console to replace or clean it right at the evaporator coils.

The important note is that you have to be careful and make sure that the hose is going down the center vent duct and not curving back toward your face (I learned it a hard way - luckily with eyeglasses on).

So, use flashlight and ****WEAR PROTECTIVE GOGGLES WHEN USING *****

Product worked well. The problem is getting the hose down the correct middle vent on a VW Touareg. The odor is gone. I used this product about two weeks ago and the musky odor has not returned. More instructions to better suit your vehicle would be helpful.

Works exactly as advertised. I searched the web quite a bit before purchasing and there is only one other product like this. The other product is not directly injected into the vents, rather is "inhaled" by turning the system to re-circ and then putting the can down by the passenger foot-well, where the air intake is.
Because of this, along with other reviews, the I chose the 1Z system. Simple to use and in fact removed the musky/foot odor smell. Only applied the foam yesterday, so no long-term review to share.
One word of caution is to make sure the tube goes down as far as possible. My MB C300 closes off all vents until the fan is turned on, at which time the internal lourvers open up. Took me using a flashlight to notice this. If I hadn't turned on the fan for a quick second, I would've only sprayed the foam into the first 3-inches of the duct work and would've wasted the can and still had odor.
