    This is a great little unit. Compact yet powerful. I like that it still has a legacy type A USB and type C. It works very well in my vehicle and is pretty quiet.

    Works as described, makes some minor noise but to be expected from a device as this. Have another product that is much noisier than this one. No real bother.

    Works. But the staff was horrible. Staff on the floor ignored us and helped others. Until someone who actually knew where the product was located was able to assist.
