Summary: You will be hard pressed to find a keyboard with as good of features, build quality, and ease of use for the same price.
I have been looking for several months for an entry level split keyboard, however, I was not willing to learn how to soulder, and I wasn't willing to spend more than $300 USD on a keyboard. In the end the combination of the price, and functions of the Israfel made it a no-brainer choice.
Criticisms:
I wanted a tru split keyboard. While I am able to disconnect the two sides of this keyboard, I'll need to purchase a sperate SH1.0 14pin cable to connect the two halfs (the only suppliers are in China and cost an arm and a leg to get to North America). Many split keyboards use a USB-C or TRS cable. I would recommend that KBDCraft adopt one of these two standards (whichever is cheaper).
Make sure to review the Vial Software documentation if you use a Linux computer, as there are additional steps you need to follow to get the keyboard to register.
Conclusion: If you are looking to get into split keyboards, I would put this keyboard at the top of your list. You may eventyually move to another keyboard, but this keyboard will help you "cut your teeth" first.
