I was trying to leave feedback for a later time when I have put it into use. But, packaging arrived undamaged, all parts & assembly went well enough & the unit appears durable enough for my needs, which is to make iconic key rings, badges for my makes, laser etching of small wood items. My only gripe so far is the Instruction booklet of which, needs more comphrensive detailing to address any add-ons & their connections, the electronic diagram for some parts are not stated whether they are positive or negative and their limits, which if connected the wrong way would cause the buyer to loose their warranty.
