I am thrilled by the product after several refills (about 10) the projector is still going strong, no battery problem, unlike other bought a little cheaper and have Laches quickly, so I ordered a second projector . It is given for 1500 Lumen, enough to work in very dark places (20 Watts are really useful). He would like the well advertised 3-4 working hours. Interesting possibility of charging cigarette lighter.
