Ease of use battery removal etc
Shiny finish would be better to wipe clean, yellow section is difficult to keep clean as is matt

Feels good to grip removed Siezed bolts with ease even when only 1 bar of power left
Only thing I would have liked a cover system to protect the gun against damage like my snap on gun . Time will tell how durable it is
