Easy to install and move to other cars with simple setup (can even use outside car, e.g., in a meeting), simple to use, quickly acquires connection with phone, works acceptably well (see minor negative points below); comes with both USB and car chargers (good job); holds charge a long time (weeks)Some minor negative points:1) Could use more volume, have to turn it up to max, sometimes still not enough, but generally acceptable2) Found locating the unit on the sun visor as recommended somewhat awkward some of the time, keeping mic pointed to pick up voice well, some difficulty with people hearing (depending on how much I'm using the visor for intended use - blocking the SUN); I found the included metal clip worked fine on the extruding shelf of the dashboard, above speedo/etc., better positioning of mic, easier to use without taking eyes off road; clip is padded, no worries about marking dash; works for me3) Have heard some complaints in reviews here at Amazon about microphone boom sticking in, doesn't spring out when pushed (which means you can't power the unit on); I bought a unit from a store locally to try out first, and it began doing that; returned it and bought from Amazon (almost half price)...this one hasn't done that yet, am hoping it doesn't.Overall, for the $50 I paid at Amazon, I am satisfied...not worth the $99 list you might pay elsewhere.
