Bests & Worsts Reviews from Amazon

I purchased this for my elderly dogs to use when entering our 5th wheel. The largest of the dogs is 140 lb so I needed something that was pretty sturdy and that would fold up when traveling. I placed this on the top outside step of the 5th wheel and it seemed like it might work pretty well but was quite bouncy when walking up and down the ramp. As mentioned by others, the surface is like a very fine sand paper (similar to a 200 grit--very fine) which doesn't work for the dogs to give sure footing so I placed a couple of rubber backed bath rugs on the ramp and it worked just fine. The first thing we noticed was that the middle got a bow in it (at about 2 months) which made it stick when we slit the sections together so we could not fully slide the pieces together. Then, yesterday 2/16/18, it collapsed when my dog walked down. It actually folded up about half way down the top section of the ramp. Luckily, since there were steps under it, it didn't totally collapse and throw my dog off of the ramp but it is totally unusable now. So, it worked for about 6 1/2 months before it collapsed. Note that in that time, it was not used full time but I would say it was in use for about 4 months of that time. I will not be buying this one again.
