Very good price quality 5 hours with 4 batteries since 2020 has gone everywhere has made a solid income.. I have 3 of these one has developed a small issue that if I turn it off it doesn't turn back on I have to take out the battery and it works normally again.. I don't mind because they have fallen from the ladder 10 times each..

Just purchased and I can say that it at least has the power it claims, meaning it emits enough light, as I had bought another OEM projector which claimed to emit 2400 lumens at the same wattage, but in reality, my phone emitted more light, so I replaced it with this one. Overall, any tool I have purchased from Bulle is worth its money and suitable for professional use.
