A update on the post - I went with the long neck eventually. Some pictures of my new toy,
I like to keep things organised so all batteries is labelled.
i drew a small marking to help me quickly align the battery to the tools. I am a lazy person so I tend to do things that makes my job easier.
I like to keep this tool close to me so that I can easily reach out to it to remove heavier defects after a standard polishing cycle. The portability and weight of this tool makes this possible.
Tools in action..
Having use the nano for a month plus now, rotary feature is currently one of my favorite. You get so much more control compared to attaching a 1 inch backing plate on a heavier rotary. Having use a good number of battery power tool, I find the Nano battery life pretty impressive.
Some not so good points- the trigger imo need a locking mechanism. Without this feature, I am basically force to hold the tool in a certain way. There was once I need to buff along the car roof which had a rack on, and with the rack in the way, I had to maneuver parallel to the rack and it was really a difficult position to keep the trigger engage. In addition, the body where we grip the tool tend to get warm so locking mechanism also allow us to change position as it gets warm. The orbital works well on flat area but 12mm orbit is tough to keep it spinning on tight curves even with little pressure. 3mm orbit lack quite abit of torque too.
Having said that, overall no regrets for this tool. If I am given a second chance, i will definitely buy it again. It has provided me with value that no other tools did- portable, lightweight, surgical buffing etc.
