Our products


All our devices are tested with the Phone Check software and subjected to a series of intensive tests before being graded.

Each device must pass all of the 28 tests to ensure functionality. Then, the devices go through a grading process accurately measuring the cosmetic look of the devices. Our intensive system checks the entire device, from ports to housing, to screen and corners ensuring consistent quality. The grades range from A+ to C and are described as follows:


Fully functional. These devices are flawless, with no trace of wear. These are described as in ‘like new’ condition. 6-month warranty. Unlocked and ready to use.

Every device that is sourced and received in our warehouses is first tested for functionality. The test consists of checking 28 key elements within the phone. If one of the tests were to fail, the device is rejected, returned or discarded. This ensures devices to be of the highest quality for our customers and reduces drastically the number of returns.


We constantly receive new inventory that is then tested and graded. As soon as new devices are ready to ship, they will reflect on our platform and will be accessible to our customers. Our platform is updated every 30 minutes with a new price and new inventory level.


Through our relationships with major actors in the used smartphone industry, we are able to offer a wide range of devices at a competitive price. Our prices are updated every 30 minutes and we receive new inventory, that is tested and graded on a daily basis.

Thus, even though some models may be out of stock or some prices may not reflect our usually low rate, we’ll advise to constantly check the platform. It is only a matter of time before those prices drop or that inventory is replenished.
