KeeYees 5M GT2 Timing Belt 6mm Width + 20 Teeth 5mm Bore Belt Pulley Wheel + Idler + Tensioner Spring Torsion + Gear Clamp Mount Block with Allen Wrench for 3D Printer RepRap

product as advertised

Very well made. Works as expected. Absolute pain in the butt to change out, but that says more about the printer than the belts.

I didn't need the belt tensioners or clamps for my application, so I can't comment on those. But the belt itself, the motor pulleys and idlers work great.

Great little kit for a stepoer motor project that I did. The value was good, and it functioned perfectly. Everything was accurate and well made. I would recommend to a friend.

My LulzBot Mini now being about 5 years old really needed new belts. The old belts by Gates (a brand I trust and use in my vehicles) kept stretching out no matter how much I'd tighten them. This new belt is stiffer, smoother, quieter, and so far has been keeping tension really well. These might just break if too tight vs the Gates that seemed to stretch indefinitely. So depending on your needs you may want to take this into consideration. Strength seems less, but for this application that was OK as the other benefits were substantial. I haven't used the accessories this belt shipped with, but I plan to use them for another project. Also there's plenty of extra belt left over, I only used maybe a third for both my X and Y axis.
