It seems to be quite sturdy to me. The actual spinning requires some balance of weight of the frames with honey. It can really wobble while spinning if frames aren't balanced. (It is recommended that you bolt it to the floor. A friend bolted his to boards and then stood on the boards.)The legs are not "sharp" but you could probably cut yourself on them if you are careless. A few minutes with a file would probably fix that if you are concerned.The top crank is built quite solidly. The plexiglass top panels can be scratched fairly easily, so use some care.I bought the 3 frame model and it worked great for me.It was a good value.
