VERY POOR product quality / the scroll wheel is stiff / when entering a new channel it gets stuck, so you enter several numbers instead of one. ALL knobs are tight. When you change channels, you get thrown back and forth several times. You press the button several times and nothing happens. You have to PRESS FIRMLY most of the time or nothing happens. waist money. Real Rating NO STARS / Product update 03/26/2021. This piece of poo is completely gone, even with new lithium batteries. DO NOT BUY as this is the CHEAPEST of the CHEAPEST.
