This time I am reviewing the GP901 from www.goodprophets.com The GP901 is very similar to the traditional DSE901 and you can even swap the parts from each units. So if you have some old DSE901 batteries and just want to try the GP901 atomizer, then you can. The only big difference I found was the price. The GP901 is a less expensive kit compared t traditional DSE901′s. Check them out over at http and tell Rob that Kalojado sent ya! And be on the lookout. We will be having a contest very soon for a Kensington powerpack and an 808 passthru, courtesy of Rob at Good Prophets!
