The smd kit challenge is a great way to test your soldering skills. but what would have made it even greater is if all the components (leds and resistors) where 0201 for those of us who want a really good challenge so as to improve those skills and challenges that we rarely face in soldering for a hobby. i wish the pcb had a key ring case so as to protect it from being shorted from any metal from any keys which it might come into contact with. perhaps tindie might look into doing something like that. being in the UK the delivery seemed to take for ages. maybe selling your product on amazon might make things a bit quicker. i really enjoyed putting the components on the pcb but once the 0201 components where soldered down all the rest seemed a breeze to put on. if you really want to challenge us tindi give us components (resistors and caps) with them all being 01005. this will i feel will really challenge those of us who take their soldering seriously and enjoy improving their skills in the art of soldering. great kit, but short lived challenge when the 0201 components where soldered down.
