i have an 801 on my 5v box. i actually built 3 5v box, 1-901 and 2-801. personally, i like the draw of the 801 box. im using joye 302 attys on it and its a monster. i dont know why but dse801 and 901 attys only last me about 3 days. im using the same joye302 attys on my 801 5v for about 2 weeks now and it still going strong. i love this atty. i was popping 801 and 901 atties left and right. im glad somebody told me about joye302 atties.
