They are step by step and easy. My kit did not come with Desensitizer so ...
UPDATE: 7 days use. After writing the first use review I was contacted by the seller, They were great! explained that I could do a 5 minute directly applied to teeth with swab. I can do 5 minutes while getting ready in the morning. I did this 3 times with substantial whitening.  They are not hollywood white (I think those teeth are made of porcelain) but they are stain free and look great!<br /><br /> I read other reviews that said they had adverse effects with sensitivity and burning/white gums. I did not.<br />I thoroughly read the lengthy instructions. They are step by step and easy. My kit did not come with Desensitizer so I skipped the first step. I boiled water and put the mouth guards in while holding on to the handles, the instructions said no more than 3 seconds and they are not kidding, I went 7 seconds and they were very shrunk, but I have a small jaw so it worked for me. I would suggest doing one piece at a time as they do melt/stick together in the hot water and in the mouth once you bite down. The instructions talked about Vit E to rub on the gums so the whitening doesn't whiten your gums, my kit did not come with it but it did come with 2 swabs, I guess to apply Vit E. I broke a fish capsule and rubbed that on my gums, seems to have worked. The light you use a bright blue color, standard whitening light, I will say after you have the<br />mouth pieces and light in your mouth it is awkward and I drooled a lot. I did the process as instructed for 15 minutes. The kit comes with 3 vials of whitening gel. I used a small amount to test sensitivity and so that it wouldn't squeeze out of the trays, at the rate I used the product I will have 36 applications/whitenings. So for $12 it is a fantastic deal. Now to the results after 1 use, I saw no significant difference. I will continue to use the product daily for 7 days and do an update. I also want to mention that this company has a great program for reorder, lifetime free gel just pay shipping $7.99 and new mouthguards were $1.50. I did get this entire kit for free via AMzRC<br /><br />First photo is before, second photo is after 1 treatment.<br />Instructions<br />How much I used 1 application<br />Kit<br />boiling water holding mouth pieces<br />done mouth pieces<br />light and batteries (included batteries)
