Ronlap Heavy Duty Furniture Dolly Cart - 440 Lbs Capacity Interlocking Moving Dolly with 4 Wheels & 2 Ropes - Flat Utility Roller for Furniture, Appliances, Boxes - Perfect for Home Moving, Warehouse & Office Relocation (1 Pack, Black)

I bought this to set a 4Patriots 1800 solar generator on, and it fits it perfectly! The generator is heavy, and since I bought it for my elderly parents to use, we had to figure out how they can move the generator around, inside the house and outside to charge it, and we bought this little dolly and it works perfectly. They can either pull it around by the handle on top of the generator, or use the strap the dolly came with to pull it around. The only thing is, we also had to get non slip self adhesive pads to stick on the dolly, to keep the generator from sliding off when they rolled it on carpet. It works so well now, I think I want to buy another one for myself ?used these to move washer/dryer and various other stuff so we could replace carpet with wood floors.also used to make the flooring boxes easier to move. Warning initially I was unhappy because the wheels seemed to be in place but as soon as we'd start to push the wheels would come off which is a big complaint on these.Another purchaser mention making sure the wheels are fully installed; flipped it; used the palm of my hand at the base, right under the wheels.. pushed down.When the project is completed I intend to use these for my large planters.I wante this to be a roller base for my coffee table, but the table slid on the rollerbase and the wheels stayed stationaryBought the single pack dolly and it had wheels that screwed on with four screws for each. I was happy with the sturdiness, and so ordered the 4-pack. The 4-pack came with insertable wheels that are a PITA to insert, and unless they are fully inserted, they will fall out. Just to be sure, I used Gorilla Glue to finally keep them in place.I liked the size and being able to hook them together if I needed a bigger oneI cannot be more satisfied with this product. It was exactly what I needed and the straps were a bonus!It did come missing one wheel so couldn’t lose one of the carts.I needed to move some furniture around and decided to buy this to help. It will carry the weight, but heavy things make the wheels come loose and you're constantly having to put them back. For light use only.Stated that these dollies click together so I bought two to help move a large box.1. They do not stay clicked together2. The wheels come off.3. Surface is slippery, so items slip of them.Returned. Not fit for purpose.In essence a very good product... if only the wheels stayed in. Sadly like other customers 2 wheels on both my trolleys kept falling out, rendering the item useless. The problem is the socket the wheels go into are plastic, and they buckle out of shape. A design flaw that could be rectified if the sockets had metal inserts for the wheels to lock into. Had to buy another trolley from a different company.I have mobility issues and this was a great help moving stuff around on my own. I usually need help but this gave me a little independence.I was surprised to find how easy the wheels are slotted into the dolly, however, when applying pressure to the dolly (with furniture) the wheels move out of place, resulting in the product failing to move furniture successfully.The pressure from the furniture misshaped the holes where the wheels would attach.Wouldn't recommend as these actually don't work.Had to shift heavy machinery parts. Did the job. Top deck a bit slippery but took the weight and castor are strong. Make sure you push well home in sockets.
