VIVO Compact Hand Crank Stand Up Desk Frame for 37 to 77 inch Table Tops, Ergonomic Standing Height Adjustable Base with Foldable Handle, Black, DESK-M051MB

Hello, according to the Vivo website and the Amazon page, the DESK-M051MB is rated for only 110 lbs, which is less than the other version DESK-V101M. The M051MB also weighs 30ish lbs and the V101M is heavier at 48 lbs, so if the product weight is right then the V101M seems to be more sturdy? Can you confirm which weight capacity is correct? https://vivo-us.com/products/desk-m051mb?_pos=1&_psq=DESK-M051MB&_ss=e&_v=1.0&variant=32161679769699 https://www.amazon.com/VIVO-Ergonomic-Standing-Adjustable-DESK-M051MB/dp/B084YTJ9D8/ref=cm_cr_arp_d_product_top?ie=UTF8 What are the main differences between the two besides the weight rating and the fact the M051MB seems to be able to extend a bit more?
