Review (1/5): This device has failed just after the return period expired
This Tua Viso has failed. It is too weak to perform. The electrical adapter that was supplied does not fit the device, so we cannot use it to boost the input. We have discovered one battery brand that worked for a short time but now it is not working either. We cannot return the item. And I've been unable to contact the seller. I DO NOT recommend this product.
