Yeah I bought it recently and tried it out. I worked out great for me. My bedroom ac was leaking water. So I bought the kit to try it out but was got tied up. But since I was so busy at work I decided to just use the bag first to collect the leak while keeping the aircon turned on. It worked for me and we were able to turn on our leaking ac at night. all I had to do was empty the water the next day. The following weekend, I finally had time to clean it so I took off the filter and cover. Just replace the normal trigger spray with the long metal nozzle one that came with the kit. I just sprayed the chemical as close to the fins as possible and let it stand for about 5 mins. Cleaning the blower was a little tricker. I could not see the rotor blade so I had to use a LED flash light. (Man these things are really powerful and cheap too! I got one for $2 at $ Value Shop). Once I started applying the spray on the rotor. Man, I could see the dirt start loosening into the wash bag. After waiting for 5 mins, I used a garden pressure spray which you can buy at any hardware shop to rinse off the dirt and I tell you they all came flowing out into the bag. I never new how dirty my aircon was. After that, I turned on the ac before removing the bag. Oh and I pull up the front of the bag to catch the water spraying from the rotor. I must say it worked out very well for me. I am really grateful for this product, because 3 months ago, I paid $150 for professionals to come clean my room ac and the results were just about the same as this. In fact, the air is even fresher with this and I did not have to make appointments and wait for them or clean up after them. Although I have to admit, the spraying was a little tiring but it was worth it.
Hope I this is helpful
