I chose this kit because AccuMeth was recommended as an accurate test unlike some others, and it allowed me to sample and average four different areas with one test, giving me a better overall picture.
The four-spot sampling method would also allow me to get a result even if I accidentally chose a spot which had no contamination for one of my locations.
The test instructions were extremely clear and everything I needed was included. I didn't have to question anything or go searching for anything, except for some tape.
The only issue I had with the kit is the little plastic cup that you need to put some liquid into - it is so incredibly lightweight and not flat on the bottom so it was almost falling over just from the light movement of indoor air. And you can't hold it up because you will be doing something else. I would recommend improving this cup.
Other than that everything went just fine. I received a positive result of about 5 on the meth concentration scale. I appreciated the suggestion to take a photo at the time of reading the test to be used as documentation later.
