From its design, it betrays that it is a cheaply made mouse, however, personally I temporarily replaced my regular mouse with this one because it is wireless and silent. Its clicks are incredible and that is the main reason why I like it and think it is worth buying. The battery, at least for now, seems durable and does not have any gaps like other wireless mice might have, especially in the gaming sector. I do not consider it worth more than 10-15 euros as a purchase. I only recommend it if someone is desperately looking for a silent mouse and something wireless.
