## Customer Reviews

### ⭐⭐⭐ 







  
  
    Compact device but lacking in information and faulty link to eBook
  

*by M***O on Reviewed in the United Kingdom on 28 August 2018*

Pros: The clock module is self contained so easy to use with I2C communications once you know the base address (0x68 or 104 decimal). Not mentioned in the description is the built in serial EEPROM giving 4 kBytes of storage, this also uses I2C communications and again you need the base address (0x57 or 87 decimal), board has three addressing links to modify the base address of the EEPROM in the range 0x50 to 0x57.Cons:Circuit has built in charging circuit so it is dangerous to use the non rechargeable batteries supplied with the device, diode on the board needs  to be removed to isolate the charging circuit.No information was supplied with the unit but found schematic and address details of the two devices by searching the internet. To use the device you must know the base address of each device.There is a link in the QR Code on the card included with the delivery for the eBook, unfortunatley this does not work resulting in an error message 'There is no row at position 0.' you will need to be able to translate url to text to read this error message. Highly unsatisfactory give us a proper link not one via flyt.it that does not work.

### ⭐⭐⭐⭐ 







  
  
    good value
  

*by B***B on Reviewed in the United Kingdom on 2 December 2020*

These work great and are superb value, however i'm only giving it 4/5 because it's slightly on the bulky size, especially if you need to fit it with other components and boards into a pi or pi zero case, so if space is an issue look for a lower profile one with smaller battery, but if that's not an issue than these are ideal.

### ⭐⭐⭐⭐⭐ 







  
  
    One module out of three was faulty.
  

*by S***H on Reviewed in the United Kingdom on 9 October 2020*

Purchased to build a WSPR beacon, I was initially quite pleased to find an SN (the more accurate 2ppm) variant amongst the three units shipped. Sadly, it doesn't work. The other two modules were M versions (5ppm) and they seem to work just fine. Don't forget to remove the 200 ohm resistor or else the lithium cell will get charged (not good). Edited the star rating because of superb customer service.
