Some reviews had them as a bit chinese in construction.
--FYI
I have Lupo 200w fresnels.. they are not perfect (particularly being not centred for mass on the yoke) but still working after a year of actual work if that is any kind of recommendation
My investment in 2X100 Lupo Superpanels and 2X200W lupo fresnels has really changed my ability to light compared to my old tungsten stuff.. Im much closer to where I want to be.
Most critically the importer is local to me so I have someone to scream at if they fail - I rate that highly when purchasing non 'brand' kit.
