We use regular Ariel powder sachets in our Samsung front load, excellent cleaning, no complaints since 2.5 years.
One 20 rupee sachet of Ariel is enough for one wash with load of 6-7 shirts/tshirts, 2 jeans, socks and undergarments.
It spins at 1200rpms with full load, which is pretty fast.
We installed ours in kitchen ourselves. The so called 'balance' problem is very easy to do as the feet are adjustable. If the water, drainage and electricity connections have been done anybody can install it.
