Since I got it, it has been perfect. Of course, it is not used daily. It seems to be very well made.

Well, another "Chinese" product story. And even though Sencor claims to have a Japanese heart (once...), in essence it is just another private/white label brand from the Czech Republic, with low-cost products. Just like most German, Dutch, English, etc. brands, they have transformed into sound/video and household appliances.
What bothers me every time with Chinese products (and I regret it again) is that, although they have all the specifications and capabilities on paper, the implementation is lacking. And damn it, they are only a fraction of their cost away from delivering what they promise.
I have bought and used many radios (transistor radios and larger ones) since the "needle" era, in bedside "radio-alarm" tables, to today's "PLL" radios. Almost all of them, especially those with AA(A) batteries or rechargeable Nokia batteries, do not sound good or have good reception.
I saw the size of the SRD 3200 and decided to try it. The same or similar OEM/ODM must exist in other brands (Akai, etc.). I did not see detailed reviews on Greek websites (only positive ones), but whatever I read on foreign ones (using Google Translate) is confirmed. It attracted me for "bedside, sleep" use, the size (208 x 164 x 63 mm), the 3" speaker, AC 230 or battery operation, and the Sencor "tradition" in radios (reception, sound).
The good things:
+ It has a very good rubberized surface, like suede, with a good feel and does not leave fingerprints, beautiful design
+ Small but readable LCD, backlit, dims after a while, ideal for night, bedside!
+ Volume button on top, with a rotary encoder (endless), no problem with dust, "scratches" in the sound
+ Snooze function, pressing the volume button on top, the same trick activates the sleep timer, adjustable
+ Bluetooth works well, USB and micro-SD ports, headphone jack
+ Lightweight-portable, only weighs a few grams with the 3 C-type batteries
The expected things:
~ Better sound than a transistor radio, but not Sony, Philips, weak bass, "dull" treble
~ Satisfactory volume, at around 1.2W the sound becomes "tinny"
~ Relatively good reception, the antenna works (although it needs adjustment in electronics), not Sangean, Tecsun
~ The small buttons in a circular layout are hard to read at night, and there are no radio memory buttons
~ The power plug (double "omega") comes out vertically from the back (instead of angled or from the side), limiting space
The unacceptable things:
- When operating with the power cord, the built-in transformer makes a loud buzzing noise, heard throughout the room!
- At the lowest volume 1, the sound is quite loud for sleep, it can be heard in the adjacent room!
- It operates with either power OR (exclusive) batteries, with the cord plugged in but not in the socket, it does not work with batteries
- Due to the above, if it is plugged in (despite the buzzing) with batteries and there is a power outage, the alarm is useless in the morning
The design and product management went well, they took a chipset with PLL tuning, digital volume, and made the product! Because I know something about electronics, a transformer without buzzing, slightly better antenna adjustment, slightly better speaker and sound cavity, true or semi-logarithmic volume, "OR" function for power or batteries (with clock/alarm preservation), and optionally, buttons for 5+ presets, would not cost the manufacturer more than $1 and would make the product better than Sony's at 2 or 3 times the price!
That being said, I am tired and ashamed to return it. What I will do (with no guarantee) is to "open it up" and try to fix the sound, minimal intensity, and battery backup. I will also check the rest (USB, headphones) and will come back.
