at Comic-Con, i either lost my Eclipse SD-9313 - Video Game Screwdriver Set or someone stole it right from under me. there was much going on while i was trying to clean a rare virtual boy game on the fly. i think i placed the small plastic box on the vendor table and forgot it. i'll miss those 20pcs. i used every bit from the 4.5mm to each pH000, PH00, PH0, PH1, SL2.0, SL3.0, T4, T5H, 6H, T8H, T10H, T15H, T20H, HEX0.7, TA1.7, TA2.0, TA2.3, TRI00, TRI0, and TRI1. anyways that was then, about a few days ago i received the 103pc set in the mail. so far i have used the Nintendo 3.8mm/Nintendo 4.5mm Security Screwdriver Bits, magnetic handle, pH1, PH2, SL4.0, SL5.0, SL6.0, T10, and the X-BOX T15. I am well over impressed with the amount of bits. I am even more stoked about the small case.... and even happier about the fast shipping. I am thoroughly pleased.
