I have now owned this butyl coating machine for 8 months. I use it on a daily basis and have made well over 2000 items, meaning the cost of produce the IGUs each is around 100 cents. How can that be a bad thing? I haven't upgraded or changed anything. I have upgraded my review to 5 stars, because even though there were some software issues in the beginning, there is literally no better machine for the money.

 Great customer service, very responsive to emails, living-videos and helping sort out any equipment's issues. This insulating glass production line is well built and easy to use. I absolutely love the finished work. Very easy to put together by after-service engineers. Took me about 3 hours to put together and another 30 minutes to figure out how to use the software. The price was good for a glass processing beginner.

 I purchased this insulated glass production line how to videos and learning its pros and cons in advance. Equipment assembly was sort of easy with the instruction book. The operator software that comes with it is easy to use that. I have done a few tests for insulating glass pieces with some examples and a couple of my own creations. It worked well and resulted in smooth and clear patterns. So far it is worth the money.
