### ⭐⭐⭐⭐ Great accessory for all my devices
*by R***N on 26 November 2025*

Its a nice keyboard with wireless connectivity (1 with a dongle, and 2-3 other only with bluetooth without any dongle).

### ⭐⭐⭐⭐⭐ Critical instructions before you use it for the first time.
*by A***Y on 4 October 2025*

Critical instruction that the product packaging leaves out : Long press the BT1 or BT2 on the keyboard for the device to be visible in the list of available devices in the tablet / mobile phone when pairing for the first time. Else, the Optimus keyboard may not be visible. Pros:The product is excellent, good build quality, keys are distinct and the absence of rechargeable battery is actually a huge plus. You can always change the Duracell AAA batteries whenever needed, all by yourself. And no need to keep charging now and then and then keep anticipating when it will run out. Cons: Does not have the space/gap to insert the tablet / mobile, which is available in its higher version. The number of keys is lesser compared to a full keyboard, available in its highest version. Absence of a rechargeable battery may mean higher costs for heavy users. The keyboard stands for higher inclination is unavailable. However, it's current inclination itself is not bad either. The shortcomings mentioned meet functional requirements such as compact, ease of use and most importantly cost effectiveness. At this price, it's absolutely "paisa vasool". And delivery timing and packaging is absolutely marvelous.
