i assumed i would be reading and studying and failing to produce anything for a long time.  i had a great time building the kit with my son and we were printing the next day.  only one obstacle with setting the first layer thickness.

If you have no mechanical exp, don't try to use this. I ran into a lot of things that had to be done since I am printing ABS. I still enjoy using it though.

RepRap Guru review

For the buck, you get a whole lot of bang.  Any issues I had with troublesome parts were quickly resolved by the Guru guys and replacements were sent to me no questions asked.  Nice little unit!

Always use it with PLA with excellent results. It is essential to adjust the height of the bed before each use and use a good adhesive (type of hair fixer)
