I have purchased several other brands of storage cabinets over the years and they just haven't held up from delivery to use. I purchased the New Age product and when it was delivered it took two strong people and a dolly to move. Once installed where I wanted it and after putting items in it, I'm well pleased. Yes, it's heavy, but well built. I especially like the lock. Although you can put the unit flat on the ground I suggest you mount the adjusting legs on. Unless the floor is absolutely level there will be a little sway and it may rust without the adjusting legs. The legs will keep the unit off the ground and it will be easier to level and move into it's final resting position. I will be purchasing addition units of various sizes as time and cost allows.
