this is my second ramp from Titan ramps, I had purchases a portable one that actually cost more ramp off amazon that lasted with dachshunds using it one rated for 600lbs it folded in center well after a year bolt broke in half on that so called 600 lb ramp with just dachshunds using it since it acting like ti would not hold me pushing my mom in wheel chair up the ramp from garage to house. Titan is much better made and with it only folding in half suitcase mold it is 1000 times better then fast fast shipping. so buy for best titan the suitcase ramps are strong sturdy
