Went for this PSU as a result of much research on mid-power units. A shed load of 'flying leads' .... more than enough for most modern PC's - nice unit - a proper power supply with good build quality - does what it says on the tin!
I bought these for grinding dried herbs and spices as well as salt and pepper as they were listed as suitable for such purposes. They are underpowered for herbs and spices and continually got stuck even though the batteries are at full power. They are ok with rock salt or pepper corns. The trouble is if someone is seasoning their lovely hot steaming supper, the moisture again clogs the mechanism. Sigh!
