Logitech has created some great mechanical gaming keyboards at affordable prices, which makes it somewhat disconcerting that it would also produce such a sub-membrane model. The Logitech G105 ($60) is not terrible as the membrane keyboards go, but it's not the best choice for people who want to play at anything more than a casual level, and it's a moderately expensive choice for those who do.
The G105 measures a respectable 19.6 x 8.8 inches, making it slightly smaller than the Corsair Vengeance K95 (21.5 x 9.6 inches) and larger than the Poseidon ZX (14.3 x 5.6 inches). If your desk suits the regular office keyboard, it also matches the G105.
The G105 ran the standard game battery test as well as any membrane keyboard. Without any big issues, I played bits of Counter-Strike Global Offensive, but nothing stood out as extraordinary either.
Mashing keys repeatedly in Dota 2 was still working, but did not feel as responsive as a mechanical keyboard. Whether tactile feedback has a significant impact on how you're playing is a fair question, but there was very little to be had in either way.
There's really nothing wrong with the G105, but it's hard to find any reason to recommend it, either. Membrane keyboards are an inexpensive alternative to a small range of mechanical choices.
