Review on KeLDE 2 In 1 Cordless Staple Gun/Nail Gun Kit, 2000MAh Li-Ion Rechargeable Stapler Battery Powered Brad And Pin Nailer For Upholstery, Wood, Crafts With 900Pc T50 Staples And 300Pc 5/8" Nails by James White

I bought this for my wife since the manual staple gun is quite difficult for her. She's reupholstering chairs. Upon arrival, I tested it on a flat piece of wood. Staples penetrated just fine & evenly, with no problems. She tried learning how to use it on the same piece of wood, again no real problems although I found it not to be rapid or quick firing due to the safety mechanism, which requires a fair amount of finesse before firing. If you're looking for quick fire capability, this isn't it in my opinion.Starting her reupholstering, she's finding as did I that staple penetration is quite randomly hit or miss in terms of uniform or even staple penetration in that a number of staples (double digits) will be quite problematic in a row & then a smaller number will penetrate absolutely just fine. Unfortunately, we've ended up pulling out far more staples to restaple then we've actually stapled successfully one time.I have compared the results of this stapler to those of the hard manual stapler on same surfaces &, frankly, the manual stapler does a better job, unfortunately. Returning is a strong. consideration.As an addendum: about half of the included staples wouldn't be usable since they were completely flat, that is, not staples.
