Assembly with large fingers I find it very difficult at a 1155er base.
The springs on the screws habwn a high resistance when push in or tense thing and but good for themselves is because I hardly get my finger into the gap between the screw and the heat sink to push the screw into the Mother, I find the design very unhappy and would be most like only 1 star, lens 5 for the function 1 makes for mounting 3 on average.
