This mobile phone is the best I have ever bought! I highly recommend it. I have had it for 2.5 years now and it has not presented any problems. It's not an iPhone 15 pro max, but for the price of €120 that I bought it for... it's simply worth it.
Translated from Greek ·Did you find this review helpful?I got it as a gift for my mother for easy use. She uses it for calls and occasionally uses Viber. After 1 year of use, the mobile simply doesn't work. It shuts down, can't answer incoming calls, so in short, it's useless now. I wouldn't recommend it anywhere!

Did you find this review helpful?I got it as a gift for my mom, she only used it to watch movies and listen to music, after 1.5 years of use it freezes incredibly and can't open basic applications or answer calls. For a little more money, I would suggest looking at something else.

I have had it for 2 years and I haven't encountered any problems. We're talking about a mobile phone that costs 100 euros. Well, okay, the camera is not great, but I don't really care about that aspect.
Well, for my own use:
Full Facebook, Instagram, etc.
YouTube for work reasons
Downloading movies
Using it as a full hotspot
And it's a beast.
Now, of course, these are personal preferencesTranslated from Greek ·- Call quality

Did you find this review helpful? Good phone but I would recommend a Samsung A generation with the same money, even though the design of the phone is a copy of the Samsung A02. I wasn't particularly satisfied, it's better to go straight to Samsung.

Did you find this review helpful?I have this mobile for 1.5 years, and I have a total of about 4,000 photos and videos, and I still have 500mb left. As time passes, the camera gets worse, so when I got it, it took good photos and videos, but now everything is blurry and bad. If you want a mobile at a good price for less than a year, then this is the ideal one.

Well, the mobile phone is worth the money, the only complaint I have is the rear speaker that loses sound and the charging is slow if you charge it during unnecessary hours. It is good for anyone interested in buying it. The battery takes about 2 hours to charge, but it is good. I have had it for 6 months and it is good for daily use. I can say that gaming is relatively good

The sound on calls is low. The other person can't hear you well on speakerphone. The touchscreen gets stuck when pressed and often needs to be pressed again. Slow charging. Not a good choice for me

Very good mobile for its price. After 6 months of use, it feels like it just came out of the factory. The only thing that concerns me is the fingerprint sensor. Other than that, it's an amazing mobile.

Did you find this review helpful? We are talking about a mobile phone that costs 100-130€, so based on that, it is worth it!!! You don't expect the speed of more expensive phones!! It is good for social use and you don't care if it breaks! Average photos, bad videos!! But as we said, for 100€ it's great

Did you find this review helpful?The xiaomi redmi6 that I had performed better even though it had 3gb RAM instead of 4gb and a processor of 1.8Mz instead of 2.3Mz. The positive thing is that it has more memory (64 instead of 32 that I had), definitely a better camera, but the negatives are the large screen (for my personal preferences). I would expect the battery to last longer as it is about +40% of the xiaomi (5000mah instead of 3700). Finally, my old one (VERY SATISFIED) I bought it 3 years ago for 110E, I hope this one will also serve me as well... Generally, based on my research, it is quite honest for the time (105E) and for someone to get something significantly better (e.g. more RAM, processor, and internal memory) they have to spend over 150E.

15 months of use and if you add two more applications, everything freezes! It takes a long time to execute the applications and there is a chance that it won't show who is calling you or you won't be able to answer!

Did you find this review helpful? Personally, I want to share with you my personal opinion about this product. Nowadays, it is perfect in terms of its features. It takes very clear photos and has a beautiful screen without unnecessary words. I have had many mobile phones and properties in my hands, and this one is very good. The battery is perfect, but the only downside is the speaker. It's not that it doesn't work, it's just not the best. Personally, I paid 130€ and I am fully satisfied! I hope I helped with my review!

Did you find this review helpful? There isn't much I have to say. The camera is fantastic, very fast, and one of the best value-for-money phones on the market. Although it says the charger is only 10W, it goes from 20 to 100% in about 2 hours. Also, it lasts about 1.5 days with full use. In the specific photos, I am in the beautiful Nafplio, so it helps the situation a little...

Did you find this review helpful?It was purchased for an elderly person who was looking for a cheap mobile phone. It was bought for 120 euros with 4/64 storage.
The battery lasts for a full 2 days with mainly browsing data. The camera is very good with nice colors. It runs all applications quickly. It's worth the money!
Also, the mobile phone is compact and I have seen videos before buying it where it is used in extreme conditions, such as falls, and the phone doesn't get damaged.
The only (-) is the speaker, which is located on the back of the phone and has low volume. But again, with a good MP3 ringtone, you don't have a problem.Translated from Greek ·- Call quality

It is a very good mobile phone and for its price, I would say it is unreal. The only thing that ruins the rating is that the GPS is almost useless. It never finds satellites (in any place I have been) etc

The phone was purchased for my mother, 55+, my friend who is 33+ also has it, it is very good in everything, just the speaker should not be on the back because it reduces the volume when you receive calls. It needs a case to improve this a little.

I got it for a relative, it's a good simple phone, good camera, good resolution, and it plays games well. It's also good for social media. Yes, the sound is not good, but it's a good functional phone with a good battery. I recommend it for people who want the basics for a smartphone
