This product works very well and is fantastic the only reason I am not giving a 5 star review is that I obviously didn't use all the liquid as it's not needed. I put the stopper back in the vial and back in the little tube. I got a new phone and went to use the vial just 3 months later and there was no liquid left. I got 2 vials and was super happy that this should last me for years since you only use part of it every 9 to 12 months...the liquid obviously doesn't even last 3 months. Opened the tube with the second vial in hadn't used yet and it was half empty. I'm waiting to see if Pela is going to make it right but it seems silly to pay that much and only have to use a small amount maybe 1/3 of the vial essentially once per year, but the liquid doesn't last that long. The actual product works wonders and I really want to keep supporting this company!
