What is Reddit's opinion of DEWALT Hole Saw, Standard, 3-Inch (D180048)?

From 3.5 billion Reddit comments

I am about to install one in my garage. It is being shipped to me right now. supposed to arrive in the next few days so I'll likely be installing it on the 25th-26th. The one I ordered is: https://www.highseer.com/high-seer-inverter-mini-split-ductless/ductless-mini-split-heat-pump-wys0018-17.html

These are tools you will need (links are to the versions I bought):

• Drill
• 3 inch hole saw bit (and a mandrel for it if you don't have one)
• a pipe cutter (look in plumbing section at homedepot/lowes)
• optionally a pipe bender (plumbing) Makes for an easier time routing the pipes and makes a more professional look.
• flaring tool (plumbing)
• torque wrench + crow foot flare nut (it's a torque wrench bit that allows you to use it on flare nuts, haven't bought mine yet) If you don't yet own a torque wrench, you'd probably want to go with 3/8 in for cheaper bits. I already owned a 1/2 inch one.
• manifold gauge set
• likely will need to buy r410a adapter for the gauges as the ends it comes with will likely be designed for car AC systems.
• vacuum pump There is a cheaper pump at HF, but it doesn't get the vacuum as far down. Almost always can find a coupon for 25% off too.

I purchased everything I needed at amazon/lowes/homedepot and I bought the vacuum pump at harbor freight.

EDIT: I forgot to mention the electrical related tools but am too lazy to dig up links for those. There is an install guide on someones blog if you wanted an idea of what is involved: http://www.hvachowto.com/2018/04/08/how-to-install-pioneer-12000-btu-230-volts-ductless-mini-split/

If I were you, I might invest in a Hole Saw. Just a suggestion.
