VEVOR RULES IN \"MY BOOK\". Too many of the 6-7 MFG's. out there are just sloppy - to many missing parts in final production/shipping, cheapS PLASTIC TIRES. I cannot EVEN count how many MFG's & Models I researched, but VEVOR had BEST REVIEWS, STATS, INSTRUCTIONS - INITIAL HEIGHT ADJUSTMENT LITTLE ODD, BUT I GOT IT. WISH i HAD BOUGHT ONE OF THESE 20 YEARS AGO!!!... IF YOU ARE DOING A LOT OF REHAB ON HOME, UPGRADES, CONTRACTORS ESPECIALLY, WE HAVE HAD 3 HERE IN PAST 8 MONTHS 2 of 3 never pulled out a magnet to cleanup after themselves. At full height this 50lb MAGNET picked up old metal bars 5\" to 13\"L x 3/16\"Thick x 1.5\"W & 3\"- 6\"x 3/8\" to 5/8\" bolts, huge nuts, nail spikes, shreds of sheet metal all sorts, nails/screws galore. REAL RUBBER TIRES! TREADS - GREAT!!! Thanks VEVOR, GREAT PRODUCT, GOOD JOB. 02birdog - Oscar-Deuse over & out :-)
