The best thing about sensanetworks was being able to have access to all kinds of equipment at once which made it very easy for my team's project management as well! Not much but I do wish we could just see more info with our devices so you can get an idea what kind or sensor your device came from before purchasing one if needed in future projects where there may be problems like this (for lack of knowledge). It would help immensely when doing research into different companies who makes these types or products available especially since some are expensive!! But overall its good stuff :) We were using them during construction time mainly around water meters/water usage etc.
