My CarpetKrin strips are installed and very effective at preventing near misses, aka falls, which we constantly had on the steps of our brand new home. Now we don't even think about it anymore. We feel planted and confident walking on the carpeted stairs. What impressed me more was how this company spent time with me on the phone to help with installation. I never felt rushed and I feel they cared enough to assist someone with very limited mechanical skills. I highly recommend this product because it works brilliantly and this company goes above and beyond to service customers.
