My opinion on my EZ Cloner was:
For sale! Cheap!

I sold the silly heavy bulky fussy thing and spent $35 on a propagation dome and heat mat, another $10 on a bag of rapidrooters, and am happy as a clam.
100% survival the first try.
Seriosuly... under 'advanced' I think- the who has the best cloning technique thread... totally trouble free.
