this thing is awesome for the price! I had a few ephro kayfun style clones.. and they were decent.. but I always struggled with airflow... the Lemo addresses that... the only con that I have observed so for is that the airflow controller is a little dicey.. and spins maybe a little too easily.. bottom fill is also a little annoying.. but again I can live with that.. I love this thing so much I am ditching my Kayfun clones and picking up a few more..
