Title: Poor range. Poor battery life.
Review: This unit's range is no more than 30 feet, definitely not the advertised 100 yards. The batteries are the expensive lithium CR2032s which do not last very long. On top of that they are a pain to replace. You need a small (I mean really small, not your standard #1 cabinet, smaller) screwdriver to get the batteries out, and the the screws are not captive. Luckily I haven't lost them yet. The stimulation mode is adjustable and it has a beeping mode which is good. But again, with the limited range, it's only good in the yard, nowhere else. The remote uses a 9 volt battery which lasts long and is easy to replace, but it also falls apart if you accidentally drop it on the ground. Cheap. You get what you pay for.
