I have used one of these sets for some time, so here is a review.
The wood and metal bits are pretty good, and they've proven themselves in jobs like kitchen fitting and carpentry. The metals bits are good on mild steel (brackets) and aluminium (uPVC window frames), although the set doesn't always have the needed size, an example being the pilot hole needed for the cutter used to make the tap hole on stainless steel sinks from that Swedish store. I usually use the smaller metal bits for creating pilot holes in timber for which they work well.
The masonry bits are quite poor, which to be fair is usual in this type of set, so don't expect them to last long. Carbide tipped bits, ideally on a SDS hammer are the best way to go if you anticipate lots of work on masonry.
The others items are quite useful, although not comprehensive. The magnetic bit holder is very good and the driver bits are ok, as is the countersink. The flat bits are very good, but again, the set may not have the size you need, an example being when fitting a door with a nightlatch I needed a larger bit.
In summary, you'll probably be able to take care of most drill jobs around the house with this set, but be aware that there's a good chance it won't have the bit you need.
A word of caution; be very careful when extracting the metal and wood bits from the case. The way they are stored means you have to grip the flute, which will mean a neat slice on the fingertips if you are careless.
