Have used floor staplers before with no problem but could not get this one to fire in correct spot. I'm sure it was just a matter of knowing how to adjust guides but no instructions included and could not find online or phone support. Husband and I have installed both hardwood and engineered floors with great results with other staplers/nailers. Will be returning this one. Have used their products before and loved them, I'm sure it would have been great quality if we could have made it work!
