I've been using Picronel for more than 1 year now, it's quite flexible if you get into live testing of landing pages as we're doing mostly with microsites here at TMW (www.thememegroupworldwide). It took us about 2 weeks to setup our first test but once that happened everything was really smooth after this point! We used piconal because sometimes some conversion metrics just don't want do look good so having all data available is always great benefit especially during optimization process :) If not enough people are interested while showing them an ad - no problem!! You can easily retry or even show another one! And yes there were times where results didn;t work well too though usually its fine after few hours/days :D Keeps getting better day-byday thanks also very professional support via email & The fact that it is easy to use, makes me feel safe as I am not doing any coding myself! It's also very quick at loading my page with images (which are all relevant). If you want something simple for yourself or someone else who doesn't know much about HTML/CSS etc., this would be perfect because there aren't too many things which need explaining - just click 'add image', upload an img file of whatever size & resolution you like, add some text if required...
