The case weighs 294 grams and has dimensions of 21.3x14.4x2.9 cm. The detachable keyboard (without the case) weighs 137 grams and has dimensions of 21.1x12.7x0.7 cm. The surface of the keys is 20.3x8.0 cm. The microUSB cable is 30 cm long (not 20 cm as stated in the description). It cost 6.50 euros mainly for use with a Windows 10 tablet due to its mini size. The case is made of plastic on the outside and velcro on the inside. The manufacturer/supplier's page offers a 36-month warranty for the product, showing confidence in its durability. (https://en.tracer.eu/tablet-case-with-keyboard-tracer-7%E2%80%9D-8%E2%80%9D-smartfit-black) It is not certain if the local representative/importer supports the three-year warranty. The case closes with an elastic strap, similar to the white version of the product. It would be better if there was another way to close it (clip, belt, buckle, or magnets).

There are 3 green LEDs for Caps, Num, and Scroll Lock. At the same time, a beep is activated on the Windows tablet speaker. The keyboard works fine on a tablet with Android 5.1.

The Space bar only works when pressed in the center, otherwise it doesn't function (perhaps to prevent accidental pressing of the side keys). The Windows key is missing, while the Menu key is present. The Zzz key (probably for Sleep Mode) does not seem to work. It is only a Latin keyboard, there are no Greek characters on the keys.

The thin microUSB cable requires some caution, as does the keyboard, which is made of thin plastic. It is acceptable for its price (6.5 euros including the case!). It is difficult to have the sturdy construction and rigidity of a full-size keyboard.

If the specifications stated on the bottom of the keyboard are accurate (5V-600mA) and it is not a typographical error (meaning 60mA instead of 600mA), this means it has a maximum power consumption of 3W, which will consume a significant amount of energy from the device's battery. In comparison, regular keyboards have 60-100mA.

There are 4 plastic L-shaped supports with velcro base (which can be attached in any position) that securely held a 7-inch Android tablet placed for testing and use (the case with the supports will likely effectively protect it from normal falls). However, it is possible for the protruding supports to hit some keys of the keyboard when the case is closed with the elastic strap. It is better to place a cloth or thick paper between the tablet and the keyboard supports.

In practice, in the short period of time it was used (with a somewhat blind system!), we managed to type faster than on the virtual keyboard of Windows 10 (without swype app or other fast typing app). If you have thick fingers, it may not be convenient.

Overall, it is a risk-free purchase (due to its low price) to decide if you can type with such a small physical keyboard. I consider the case and keyboard together to be a decent/value purchase.
