Delivers in the cutting power

Review by Joe on 10/19/2020

Purchased this tube to replace an 80W RECI tube, most of what I was doing is cutting 1/4" MDF, and boy this tube can deliver on that. Easy to install as it comes with a screw-type connection and so far it is performing like a champ. I like the longer warranty compare to the w2, and so far I am satisfied with this tube.
