If you're after a TKL keyboard the question is why? Travel or space issues. So I find this (and the overpriced Logitech G915 TKL) just too big. In a another post (on mice and traveling) I say I have have used a Vilros keyboard+mouse for over 2 years. The keyboard is a little small, I'd like one 2cm or 3cm longer but it works for me where space is an issue. Traveling with it has been fantastic.
I would pay more for a premium product and I've tried a lot of of the smaller keyboards, at great cost. It's seems there is an almost an inverse relationship between cost and life span of the product (and cost and usability).
I've also found bluetooth drops too many characters and USB ports are a precious commodity, so a single wireless USB for both the keyboard and mouse is mandatory for me. And the best has been a cheap, little undersized, but perfectly usable Vilros.
Pity as I love the feel of a good keyboard. And having learnt touch typing on manual typewriter I appreciate the feel of modern keyboards.
