Takes time getting used to but is very good. Need to buy the SB7 Pro. Currently using SBox

Game changer

This is little device is amazing! So many features that I have always wanted in a spirit box. I added this to my SB7 and was blown away. For me what stands out is the playback function and the slowing down the recording. No more going what did they say, lol. The filters work good. I do like the high filter the most. The Bluetooth has been nice as well. I leave the APF connected to my Portal and just walk around with my SB7 in hand. My only recommendation is to buy an extra 9v rechargeable battery.
