GMK Lime is not my favorite colorway, but I paid $54 with $5 rewards and a $10 coupon and the set was in promo for $69, so for this price this is one of the best deals you can get for a complete base kit of original GMK keycaps. I do not think it is worth the MSRP of $140 though.
I purchased this set in bits & pieces. The original lime caps came from a drop mystery box order a few years ago. I was disappointed that when I tried to install the keycaps, the spacebar didn't fit. The set was missing some other keycaps I wanted like the arrow keys. I had to buy a small custom set to finish the job and it is niice. enjoy the pics!
