Got the no. 3, is a pretty good match for my brows and hair color. Smells nice and floral, is very goopy. You should have time, patients and a steady hand when using the product. When I use this product I usually leave it on over night and peel it off in the morning. I peel it from the inner brows going out towards my outer brows, and didn't experience any hairs being pulls. Also while applying the product I was light handed and faded the product out at my inner brows to soften/lighen the tint there so I wouldn't get harsh line. The tint last about 4-5 days for me. The tint is really pigmented during the first 3 days, however as it fades, the color started to turn a yellowish brown color on me. Not really concerned about that though as I can go back with a brow mascara to fix the color. Definitely saved me the time when filling in my brows as I got to the 4th and 5th day, didn't need to fill my in brow for the first 3 days. So long as you are careful when applying the product and patient, this product should be fun and easy to use.
