UPDATE: 6/20/16: We have now owned this PetStep Folding Pet Ramp for about 3 full years, and just wanted to let everyone know who may be considering purchasing this ramp, after 2 to 3 New England winters outside in various amounts of snow, freezing rain, sleet, you name it, I can confidently say this ramp shines! Day in and day out, the weather doesn't affect this ramp. Sure, the sun may have altered the khaki color a bit, but it is still as perfect as when we purchased it. My beagle uses it every day to go up and down our deck steps to our back yard. We also carry it with us for our motorhome. She uses it on the steep motorhome steps, and it's easy to fold in half and store behind our sofa in the back of the van. We were fortunate to purchase this used, and it looked brand new, so we really got a good deal on it. I'd pay the price listed now if I had to, but I have a feeling (knock on wood) that this ramp will outlast us all! END OF UPDATE. First, let me say that I've only had this ramp for approximately one week, and normally I don't believe in posting reviews so quickly. I planned to post a review of this product in about a month, but had to post this early in case it helped someone else in our situation with their dog. So here is/was our situation. Out of the blue one day while on vacation, my dog screamed in pain when walking up the 3 steps to our motorhome. It was so heartbreaking and she ended up at a pet ER while we were traveling. She was put on pain medication until we returned home. After many unsuccessful vet visits, it was determined by a specialist that our beagle has luxating patellas (kneecaps that pop out of joint). She would always walk fine on level ground where no steps were involved. So we had been carrying her inside her metal crate up and down our outside deck steps so she could do her thing! A 25 lb. beagle AND a metal crate that has to weigh at least 15 lbs conservatively! This had been going on since this past May when she experienced her first incident of obvious pain when going up steps. I looked and researched many ramps, but this one was the only one made with a rubbery surface, although I think the entire ramp is some sort of plastic, but with incredibly good traction. I did what another reviewer suggested, laid it flat on the floor inside of the house and within a day, with some coaxing and food, she easily walked back and forth over it that way. Well, today, I decided to put it outside on the steps down to our patio, and didn't think she'd take to going down the ramp, much less up the ramp, right away. Once again, food did the trick! She didn't even hesitate, and walked down the ramp to retrieve the food, and back up again to retrieve the food, as my husband stood at one end, and I the other. So in less than a week, she has really taken to it much more quickly than I expected. So if anyone is on the fence about it, I highly recommend it, and the weather probably won't hurt it since it's made of hard plastic and rubber. It has one little latch to fold it shut, but I just carry it sideways folded under my arm like a suitcase to move it if needed. It will really prove to be a back saver for both my husband and myself!
