Review on Set of 2 Clear Stair Treads Carpet Protectors by Ghostnote Hankins

As this product comes in a set of 2 I bought 1 set first to see if it would work on my 15 step staircase. I wanted to try them out before investing in 6 more sets because they are expensive. The first set of 2 was great! So I went ahead and confidently invested another 6 sets. They sent them in two different batches with 2 sets in each box. The second set was just as good as the first. They cover the stairs nicely, are very playable and mostly stay in place, I was happy. Unfortunately I was disappointed when the third batch arrived. This plastic is very hard and doesn't wrap around the curve of the stairs at all. I've tried getting them to come in and step on the bend to smooth them out so they wrap around the bend in the stairs, but as soon as someone steps on them they come down immediately. At the moment they are just a danger and an accident can happen! I wish they were all the same plastic as the first two sets. You would be great! Disappointed because of big investment. You would be great if you just knew what kind of plastic to get. That's why I give 2 stars because the 3 sets were great!
