I won't review device itself, it is OK for money. We all already know its characteristics. But, what I really want is to praise Eleshop and UPS, transport company of Eleshop's choice. From Netherlands to Bosnia and Herzegovina for, well, less than 48 hours (ordered 15. 7 at approx 15:30, had in my hands 17. 7 at approx 15 hours), including custom procedure and for Eleshop's standard price of shiping is unheard of. I wouldn't believe it if didn't expirienced it. Local shipping in BiH can take longer. Thank you, you are great.

Works fine for a entry-level power supply unit. No complaints so far.
