Very Satisfied
Order arrived in 2 business days. Maybe 2 small blemishes, which matter not to me because my tools get banged around a lot. I am always far more concerned with the functionality of a tool. This stapler worked perfectly right out of its carrying case. I ordered another "can't-live-without" tool from CPO. Saved another very large chunk of change.

Good product, good service.
I have had several Bostitch products with good results. I haven't had this one long, but am sure it will be same service as the rest. I have had good results from Bostitch service in the past, also.

All about CPO
Bostitch quality stands by itself. I buy recondition products when possible and I haven't had any products that were not perfect until this one. The first gun jammed as soon as I shot the first staple, cleared and second staple jammed. Call CPO at 3PM on Monday and received a replacement on Tuesday afternoon. Tuesday evening I was shooting stapled at anything that moved. I can't say enough about this company. CPO is the best in my book.

Need better quality control
The first stapler I received was defective (leaked air at the trigger) so I returned it and was sent another one that was fine. The hassle of boxing up the defective stapler and taking it to FedEx was my only issue with the purchase. I have purchased other tools from CPO and will continue to do so in the future. Great prices too.

A shopper on Oct 24, 2016
BEST ANSWER: Yes, technically they can be used, but they will be prone to jam more often
Looking to reattach some aluminum siding back on to an old RV that I am restoring. The crown of the staple needs to be flush with the surface of the siding, not countersunk. Is the adjustable range of this model sufficient to do this? Thanks

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 60 days.
