Cushioning is good. However, the adhesive force of the attached adhesive tape (double-sided tape) for affixing is weak and there is room for improvement. Because the place stuck on the corner part of the dolly was peeled off.
I attach it to the corners of the silent cart purchased the other day (attached with tapping screw) and use it. This completes the perfect cart. Even in a field where restrictions are severe, this can be used without problems.
