Bosmere S18410 Heavy Duty Plant Caddie with Wheels - 16-Inch Black Plant Stand Holder, 500lb Capacity - Perfect for Indoor/Outdoor Potted Plants, Garden Decor & Easy Mobility

These are not the most attractive plant container caddies. However, if you need a plant caddy for large, heavy concrete plant containers this is the one to purchase. No question.High quality casters. The lock isn’t impossible to use - quite easy to lock and unlock but it still holds tightly when locked. I find I most often use my hand to lock and unlock and I can do do with slightly crippled fingers. IMO, the lock deserves high marks for accessibility allowing people lacking finger, hand, and wrist mobility to use the product.A great feature for people to whom details matter: I love the slightly raised markings on the top of each “leg” of the caddy. These enable you to have the container centered on the caddy.The price might well cause one to consider other choices. Understandable. But if you need a heavy duty caddy, I don’t think you’ll be disappointed with the value you receive when purchasing this one. This one meets “Buy it for life” expectations.
