Even on a few watts all in one chips will knock out all the neighbours fm reception either side of you, maybe good for a farm where no one listens to fm, you can get them much cheaper but why would you? I think this is similar to one I saw in a video that was 30w, the guy did a review of it, he said it was good as long as you used it at full power! they never seem to mention the wideband noise they put out across fm
