Love these. Super easy and noticeable change.

need twice a day, I was doing once only qhich was effective too, would recommend

I've used these a few times now (not long term, to be fair - just a few days in a row) and don't see any results. But they also don't cause any teeth sensitivity and they are very compact + easy to use, so there is potential for whitening effects to show up after more time. Personally, I see much quicker, more noticeable results with Meijer brand whitening strips for just a few dollars more. However, you get more uses out of this whitening pen pack, so it's a great value if it happens to work for you or if you're a bit more patient.

So I had never used one of these before. The only reason I bought it was because it had lower peroxide strength the rest. 22% I think. Anyway, I dried my teeth....brushed some on just the front few teeth and left the house on Thursday. My teeth were instantly whiter. Much much whiter. Now its been 5 days and they are still just as white and I have not used it but that one time. I anticipate maybe touching up the whiteness once a month or so but there is no need for anybody to use this daily. I experienced no sensitivity nor any need to use it the next day or the day after that. My teeth are staying white from that one application. I anticipate using this maybe once every 2 weeks or maybe even once a month. It works marvelously. Ask me any questions you may have.

Horrible product I think this is just peroxide it's not gel for and for 2 it's so liquid you can't brush it on your teeth its not 5 either 1 of them is just regular supposedly sensitive toothpaste this is literally the worst teeth whitening product I've ever purchased.

These PamBoo teeth whitening pens are great! I was pretty skeptical because I have the expensive custom made trays from my dentist. I don’t like using them because they make my gums AND my teeth hurt. Before using the PamBoo pens I put a little Vaseline on my gums just in case. I applied the gel and I could actually see the coffee stains coming off. I did take a cotton round and fold it and then folded it again and put it between my front teeth to remind myself to keep smiling slightly for 30 minutes. I did this because I didn’t want to risk getting the gel on my gums. Then I did some busy work so the 30 minutes would go by quickly. The results were better than I expected and I’ll be doing a treatment for the next week. Be sure to take a before picture so you can see how it’s working. I’m a happy camper. A+++

It’s just liquid I thought it was gel. I returned them

I'm using this product for the first time ever due to years of drinking tea daily. The pen brush an twist to get gel into the brush end makes for easy application to my teeth. I brush first wait a few minutes dry teeth with tissue open pen twist gel into brush an apply whitening gel hold gums off top teeth for 30 second an repeat application to bottom teeth again holding lips off teeth for 30 seconds. I then put in clear liners 15 minutes after application. Im doing this process 2 times a day which is recommended by the manufacturer. It's only been a few days but am noticing a bit of a difference in whitening. I will wait for at least a week or two to provide more details but appears to be promising. I don't notice any gum or side affects or adverse flavor in my mouth after applying the gel.
