The column is excellent! The charge keeps well. Hours for 4 work was discharged by 10%. The lantern is bright enough, though, it shines like household, but I'm happy. The case is rubberized, I think that replaceable; sticky, collects dust on itself. This is visible from the photo. Separately I will say about the delivery. There are no complaints to the store! Have a question to IML company. The order is made by 05.05. With shipment from warehouse in Moscow. 09.05. The parcel was in Krasnodar, 13.05. In the region of delivery-in Sochi. And only 18.05. After the letters and calls "to all instances" the order was brought. Week "freeze" the parcel in one small city, well, несерьёзно. And called almost from the delivery address, in 5 minutes, not for 30-60 minutes, as indicated on the company website. The Courier is cheerful, I did not become a gun)) in general, the column is multifunctional, what was important for me-sound, lantern, powerbank-works! FM radio catches. I advise you to buy, I recommend the seller. Bike testing still has to be done.
