The safety wire (.041) arrived on time as stated on the order. The spool itself is packaged well for ease of dispensing. It will not unspool like traditional spools of safety wire. Great product!!!

Product is great, exactly as advertised. Fast shipping. Only complaint is the 20 + dollar shipping charge for 3 Rolls of wire.

Sportys $17.95, Spruce $9.95. Sportys refused price match citing different manufacturer. Sportys Flight Crew free shipping worthless(refused 6 mos. refund also saying Id used it!) NEVER again Sportys! Wasted $18 on Amazon for a pkg of 3 cheese cutter wires that all promptly broke. The 0.020 wire. EXCELLENT for replacing cheese cutter wires! Strong and works easily(0.032 too thick)

As always, the tech help by phone was excellent in helping me order just what I needed. My order arrived even earlier than expected and everything was there. I can’t imagine where GA would be without Spruce. They’ve kept me supplied with quality parts and materials at a fair price, and on time delivery. A+
