Comments on RF & Microwave Toolbox lite for Android

★★★★★ Computer Machine. Description of a computer system.
★★★★★ Nice Very useful app for electronics students
★★★★★ Apps havr vome so far.... Do TOO DEVELOPERS FROM THE LAND OF SUPER AWESOME COOLness.... ty so much. Apps for adults that work n not play rock! (sad ppl actually have time to play games like Tetris n omfg! Solitary type mind waste. So sad. Ppl can't use THEIR POWERS OF" "IMAGINATION"=== which I.m.h.o. MAKE US ALL "the GODS!" (Yep. I just wenr there... u go get on ur knees n pray to ur lul fantasy dude. Hey-while you're on ur knees, CLOSE UR EYES, OPEN UR MOUTH REAL WIDE-NOW DON'T BE SCARED.... HERE IT COMES... PLUNGE!) Relig
★★☆☆☆ All of you info. Overlaps I can't use it (moment)
★★☆☆☆ Everything is all squished up on my Evo's screen. Unusable.
★★☆☆☆ Cut Throat Ads A little bit of good info.
