Item : B0000224QO Customer Reviews Small & Powerful - HVAC applications by .. () Cant get 3/16" 20 gauge crown staples anywhere. Even major fastener supply houses dont carry anything accept a 9/16 leg which fold over rather then sinking into hard wood. The case is also poorly designed..seems like its meant for another bigger stapler. This stapler doesnt fit properly in the mold. I bought it for stapling sheetmetal panning into manufactured beams..which are very hard. Its alot easier then neumatic staplers but 1/4" 18 gauge staples would be alot nicer then 3/16" 20 gauge which is the only type this gun fires. Its also very quiet and fires quickly. a good value! by .. jay miscovich (Pittsburgh,Pa USA) I have been renovating realestate for over 23 years and have owned various electric staplers.this stapler sinks the staples totally into wood at least 90% of the time. i especially find it VERY GOOD for carpet pad and carpet installation! its recovery time between staples is VERY quick(about 1 second) and it rarely jams. if it does it clears easily ....overall i like this stapler very much and would purchase another in the future!
