very easy to install

Bullet 500 standard

Easy to install. Looks good. To mount 25mm highway footpegs, you'll need a small piece of electrical tape, and it works. The price is reasonable (the welds aren't perfect, and mine arrived with some rust spots at the top...).

Good and of good quality.

Good quality, but it's a shame the screws and spacers are too short to fit with the pannier racks.

excellent

Alright

The welds are good, the paintwork a little less so, the mounting brackets are the correct thickness, the screws are adequate, and the parts were well protected in the package. Durability remains to be seen with use. Considering the price, there's nothing to complain about.
