Just the kind of disruptur or dampner that I'm in need of to test some old n dying distortion units. ### ⭐⭐⭐ 3.0 out of 5 stars Basic hub with no external power supply provision *by C***W on Reviewed in India on 17 January 2018* Product works fine as a basic usb hub. The built in cable is about 50cm long and the product itself is a tiny 18mm x 18 mm x 65mm. There is no provision for an external power supply - only USB power. For more power the iBall Lappie Piano 423 High Speed 4 Port 2.0 USB Hub which supports an external power supply. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Value for Money!!! *by H***T on Reviewed in India on 21 December 2018* It's working great all 4 ports USB works together but the only thing is the wire length should be more bigger to connect to the CPU a part of it great product.....
