I recently received this compact Bitcoin mining device and can confirm it delivers a smooth and stable performance at approximately 100 GH/s. Note that it ships without a power supply unit, so you'll need to purchase a high-quality PSU (15W+) separately, as the device is quite sensitive to good power source. While it incorporates a fan, operation is practically silent.

The unit does have a somewhat beta version feel - the settings interface lacks many timezone/location options, the display fonts appear rough, there's no option for 24-hour time format or alternative date formats, and the screen surface scratches easily. Despite these shortcomings, the overall experience is satisfactory, and customer support has been very responsive, promising a firmware update soon.

Value-wise, the hashrate-to-price ratio ovisously isn't competitive (the Bitaxe Gamma offers 10x the performance at the same price). The unit's specifications (100 GH/s @ 8.5W @ 425 MHz) suggest older technology similar to the BM1387 chip from the Antminer S9 era, though the manufacturer claims it uses their proprietary new ASIC manufactured by TSMC. Regardless of its modest performance, it's an interesting and unique gadget that makes for a nice addition to my home collection.

It's encouraging to see new competition in this space, and I look forward to future offerings from this emerging company.
