a friend of mine bought one last year. a little pricey but a good unit. the remote failed soon after he got it. he sent it back and they promptly replaced it. (no problems since) the unit is not quite as loud as i would like, but, on a calm day or night it seems to be fine. the battery seems to last a long time. a lot of calling on a charge. it comes with a base package of calls which can be altered with your computer. the sound clarity is very good depending on the quality of your sound file.. it is very compact and lightweight. about the size and weight of a 6 volt flashlight...i myself am considering "the bushwacker" a similar caller, a little more $$.. hope this helps..
