Ever Tried Laser Module for Alignment?

[filncie]

I am working in a screen printing factory. We always used larger laser devices to make cross line positioning to fulfill various pattern design on garments.
But recently I found an ultra compact red laser module. Its diameter is only 12mm, very small, but cross line beam is very stable. It can be very easily installed on heat transfer machine, and help me a lot for drawing work.
Is there any other guys who are using cross line generating laser module? My cross line tool is quite similar with this cross laser alignment. I would like to get more shared information about this portable cross line tools. Thank you in advance.
