I have been using this product for a week and it has had little to zero effect. I was slightly sceptical at all these people reviewing the product as part of a paid reviews scheme. Notice the five star reviews are nearly all about the quality of the instructions and ease of use of the device, whereas little attention is actually given to the efficacy. I will persist (against the advice of the instructions) with it for a few more days and amend my review if there is a change. As for now I am disappointed. Read more

Don’t know if it works on corns because I couldn’t get the gel out of the pen and onto the brush. Twist, twist, twist some more until the brush head pings off across the bathroom and acid fires all over the place. Cleaned up, replaced brush head, tried again, ping, same thing happened. It’s gone straight in the bin. Waste of money Read more

I am so disappointed with this product. First of all, the liquid doesn’t want to come out.Then, after a few more twists it comes out too fast.I have used it twice in 2 days, and the corns are still there!!!I’d prefer the good old fashioned corn patch! At least the corn would blister up in a white circle and I can take if off in the bath. Read more

Whilst following the instructions you need to have the brush pointing down so that gravity and pressure push the liquid into the brush, only the brush never got wet and eventually the pressure got so much that the other end of the pen popped off because of the pressure. The pen became unusable as the liquid dribbled out of the now broken end, and as it was caustic I had to throw the pen away.Did they think this through? Read more

It doesn't work,save your money and by some corn plasters,it's complete rubbish. Used it for 12 days and corn still there,didn't even make a mark on my corn. Couldn't believe how useless it was, waste of money,very annoyed with this pen. Take my word for it,DO NOT BUY IT! Read more
