I just installed 10 recessed lights in my living room and this stripper saved me a ton of work! I used 14-2 BX cabling straight from the circuit breaker box to the ceiling cans. Just pop the cable in and tighten the thumb screw (needs to be done only once) then squeeze the handle and start your drill. Within seconds there's a clean cut of the armor which can then be easily removed. There were no nicks on the wires. Great product! And shipping was extremely fast from Seatek.Thanks Seatek..I will never have to spend time uncurling BX and using wire cutters again! Not to mention cut fingers.
