As i said they are very nice but are more resistant than double shot ?
do they last longer; do they shine less ?
I can understand people spending lot of money on unusual things (keyboards, stamps, magfic/pokemon cards) but in that case is the quality worth it.
For example two cars help you to drive from a point to another, but one is sturdy, will last longer and will give you more pleasure
the other one won't.
difference beetween a Hyundai and a BMW let's say :-)
and my car is worse than a hyundai... because i don't care.
For keycaps, if the feeling is smooth; they sound nicer and they don't wear off in months, that's ok. But double shot are fine too for a fraction of this price.
Hope for you you'll sell them; anyway.
