The ones i got were very good the only thing or complaint was they used a spherical lens for the projector beam vs the "$100s of each" aspheric and/or achromatic lenses so when lighting just the wrong surface you'd see some prism effect. Not a terrible trade off for 90% cost reduction. I'd only notice on white large reflective signs never a big distraction.
