A few months ago I needed a new Bluetooth adapter 4.0. By and large such "device" I was looking for a fast connection to the computer and the phone (honor-9) not to use the cable connection. It was decided to buy a budget model of the adapter. In the store, "DNS" brand DEXP is one of the cheapest. This adapter cost 599 rubles., although, of course, I would like to invest in the amount of 500 rubles.
Bluetooth adapter DEXP AT-BT403A – a miniature device for creating a connection between electronic devices, one of which is already equipped with Bluetooth. This means that the presented model can be provided to your desktop computer or laptop, provided that they are equipped with a USB port. Then install exchange desired files from tablets, smartphones, printers and other devices will not be easy even for the inexperienced user. The connection interface 2.0 this adapter is compatible with Bluetooth 4.0 standard. The range of the adapter outside of the room is 30 meters, which is the result of much above average (the standard radius of such devices – 10 meters).
The main characteristics of the device is on the packaging. I liked the compact size, nevadensis black color plastic case, as well as the time that the adapter works on the slide. That is, backward compatible with Bluetooth versions below.

The characteristics we focus on the large (driving) radius. Usually my devices are in close proximity to each other. I have no need for communication at such a great distance. I think that for computer communication, for example, and portable USB speakers, this adapter comes in (at the cottage in the garden, in a private home).
The size and weight.

The adapter is quite compact (my mouse is also wireless, it adapter are smaller). In form and appearance resembles a flash drive. In my old netbook only 3 USB: the mouse, this Bluetooth adapter and modem for the Internet). If you need to insert the USB (flash drive), it has no place. Need a USB hub.
Despite the fact that the device is manufactured in China, I would not say that it is made "tyap-lyap". In my opinion, all very well assembled and reliable.
Often use the adapter to exchange files. Sometimes for listening to music from your phone.
I like that the device when connected to the PC very quickly with it "binds" and all the drivers are installed automatically. Files take off very quickly, crashes when connecting does not happen. However, if I use the adapter on different devices, when you connect to the different computers that need to "establish" the connection and the adapter name is displayed on the last computer (before you send the file, I check the address). Sometimes you need to re-search the device if the adapter worked on another computer. If you do not "pull" the adapter on different computers, and to use stationary, then no difficulties arise. Device find is not necessary, it remains in memory under one name.
In the settings you can choose necessary settings. At home, both computers (one a netbook) with Windows - 7.
In the settings you can also check the Bluetooth services supported by the specific computer to which you connect the adapter.
By the way, in Windows, the Bluetooth icon after connecting appears on the toolbar at the bottom, where the clock/calendar, battery indicator, etc.
I also want to say a few words about the device. The plastic housing has a cut for fine lace. This is to ensure that the adapter can carry as a keychain without losing it. The led on the case is at the bottom (its "flashing" absolutely not interfere, because the eye is not evident). Only indicator I have is not red as indicated in the instructions, and green. Paint-lettering of the brand, with the corps is not erased (this inscription allows us not to confuse it with other apparently similar devices that are simultaneously connected to the USB port).
As a result, the device will suit me: works quickly, difficulties with setting did not arise, has compact dimensions and is collected efficiently. The manufacturer gives a 1 year warranty.
