  16. R***n

    it works.

  17. A***v

    Everything works, it’s not heated. If there are batteries then take. The only thing closed it a little.

  18. V***v

    Delivered. Soldering is not the best one. But ok for the price.

  19. A***s

  20. Customer

    You should worry more about the lid that doesn’t close well. thanks.

  21. A***y

    fast delivery to 9ja. thank you… product will be testing later.

  22. Customer

    The parcel was about 50 days, the metal part of the case was slightly wrinkled. The description corresponds. Charged off smartphone (battery capacity 3500 mah), for 50 min. The charge increased by 10%, i.e. For 8-9 hours you can fully charge. For my purposes will go.

  23. C***D

    Saglam sees no dirt, no battery, I’ll try

  25. Customer

    didn’t realise they had to have rechargeable batteries inserted. does not come as a sealed unit.

  26. Customer

    The Seller shipped this item very quickly and it arrived undamaged to the UK. The only reason I have only given the item 4* is that the item is larger than expected (ie approx. 3.5″ x 3″ or 9cm x 7.5 cm) so it’s too large to go in the small handbag I needed it for, but nevertheless it’s worth the money (if a bit ‘tinny’). No hesitation in ordering from this Seller again.

  27. A***k

    The fasteners of the front cover are very flimsy p almost immediately detached…

  28. V***v

    The quality of the case is very mediocre. The lid fits badly.

  29. Y***k

    In minsk came in 40 days. Works. Thank you very much.

  30. S***y

    All ok ..

  31. S***v

    In general, not bad

  32. P***v

  33. Customer
