3X have had Crafty units fail in 1yr, 1st @around 35hrs or so, next 72hrs, most recent <60hrs...was working fine for about a month after I let it sit in the jar pictured with the molecular sieve (not sure if this particular MS can absorb ISO, but there are MS that can) for 10days. Lucky for me I live near enough to IMPAK, that I could get single packets of MS for not much money. They do sell a MS that has blue indicator to tell you when the MS is saturated, but you have to buy min quantity, something like $25.
I dropped two 1oz packets into the glass jar that I sealed with duct tape, left most in packets, some spilled that you can see @bottom.

My suspicion this time, is electronics overheated to the point of damage. The only time I decide to not use the app, and just go by the LED lights...should have used the app as I thought I had a full charge, but in reality forgot to charge it when it got down to 1 bar status (but before getting low battery warning)...then it stopped and I checked to see the battery was completely discharged on the app, lol. Put it on charge, 1+hrs later it showed fully charged (which is wrong, since it takes 2+hrs on a fully discharged battery). Next time I tried to start it, pushed button, got red power light on the LED, app connects very temporarily> red LED goes out. No power, cannot get the app to establish a connection with the Crafty. Sent in RMA request. If only S-B would redesign this unit, using a cooler running Samsung battery, maybe the electronics would last longer
