Great product with good styling without being too large for smaller dogs. Don't let it's small size fool you, testing it on myself this collar packs a wallop of a shock. Luckily my dog responds well to the vibrate while the shock would be useful for emergencies when you really need their attention. Worked right out of the box. This specific model does not display the receiver's battery level on the remote. The collar is totally adjustable and with a little effort can be made smaller without permanently removing alot of the strap. All the features of the store brands at less than half the price.
