" ... I get maybe 30 min of talk time before the reciever just dies, so it's useless for an hour long class. ... I've tried all sorts of batteries with it, even investing in high quality rechargeable, and it doesnt make a bit of difference. ... "
" ... And battery doesn't last longer(hardly 40 minutes a pair in both Rx & Tx). ... I tried to take out batteries after one 30 min recording session, that gave me another ~10 minutes of juice another day with the same set of batteries. ... "
" ... Then about 15 minutes into the performance the new batteries quit. ... "

" ... The plastic material is decent quality for the price. ... "
" ... I wasn't too sure about the plastic casing and how well the range would go, but it is actually pretty good. ... "
" ... The case is lightweight, which also means cheaper construction. ... "
" ... However, its build quality is extremely (and I mean extremely) cheap. ... "
" ... The materials are on the cheaper side but for this price your probably not going to fine higher end materials. ... "
" ... What else is great: the mic comes in a thick, cardboard box with molded, foam padding for storage ... "
" ... I believe we tend to judge the quality of gear by its weight and feel. ... There is a case made for this item that I’ll be ordering. ... "
" ... I just want to start off with saying that this is one of the most affordable and durable options out there. ... "

" ... The headset is easier for me anyways. ... "
" ... The sound was clear, after tweaking the eq on the board and the vocalist was impressed with not having to use a hand-held microphone. ... "
" ... The headset is comfortable, but has a tendency to slide back if your head moves quickly. ... "
" ... The included headset was very uncomfortable and I had to order something different but it also includes the lapel mic which is a nice bonus. ... "
" ... The only negative thing is the receiver feels kinda cheap but it holds up very well. ... "

" ... A helpful hack I used Velcro to stick it on top of my rig. ... "
" ... The only suggestion I have is that they create a clip for the receiver so that it clips onto the mount on top of the camera. ... "
" ... I found that using a holder for my phone worked well to hold the receiver when connecting it to my camera. ... "
" ... Also the lapel is a bit large, but the mount is nice and hold on tight. ... "
" ... Bought the hand held unit and a small plastic carry case to hold both units - makes a slick little set up for use. ... "
" ... I liked the way it fit on my head and didn't mind clipping the pack on my waist. ... I situated it off the side of my hip, it didn't interfere with crunches or other moves performed on the back, or side. ... "

" ... I think there is something wrong with one of the connectors. ... "
" ... The casing is plastic and it uses a 1/4 inch plug instead of a XLR. ... "
" ... It appears to be at the mic end, wiggling the wire there causes it to cut in and out. ... "
" ... The wire came loose using it the first time. ... "
" ... The cord is also so short that if you try to route it through your shirt it is constantly pully and snagging. ... "
