Technically, the part as well as the previous top notch. Communication with the iPad Air is working properly, the battery lasts forever, and the keyboard itself is great and pleasant when writing.
BUT: As stated by many others here, the quality of workmanship has waned! Also with me the sheet (the ground quasi) bends under the keyboard now questionable if the iPad Air is inserted in the space provided rail. It is then simply a lot shakier in it than its predecessor. Can only confirm these reports.
Since it did is quite favorable in MarketPlace bought, I renounce returning because it is technically still works fine and does the job. But - especially in direct comparison with its predecessor - I am quite disappointed by a regularly quite high-priced Logitech product!
