Very impressive. Well designed. Linco makes quality rollers. I have several videos and I linked them to them with no problems. They add more portability to my cabinet table. I use them in combination with a set of floor locks with pedals. The bench weighs about 400 pounds. Interesting are silicone-based low-noise tires that shrink to a minimal width in relation to the weight. quality stock. Reliable, lightweight locks. Good value for money.
