Unit has a metal case with removable top cover, forward / backward switch, hot / cold switch, temp control dial, analog temp gauge & ready / power indicators. This is a heavy duty machine suitable for home / office and limited industrial use in some small shops and industries. I have used mine for laminating some Certificates and many credit / business size cards. Never had a jam. I did remove the entire cover to check out the build quality - very well made & fans can be added if you like DIY electronic projects. The photo I included shows a laminated parts chart for a laminator that might be this exact model with a different Brand tag. Videos for troubleshooting problems and repair of this unit (that is what I was searching for) can be found on tube sites, mostly in Asian languages.It does produce some heat (not a bad thing if kids are not around). This would be a super value if it had some sort of sheet holder or feeder for good alignment but they are not common at all on most consumer laminators. Note: I bought my unit before I found that Amazon was selling it.
