Review on Underground Containment Aboveground Waterproof Rechargeable Dogs good for Training & Behavior Aids by Amber Vue

First let me tell you what I like. Remote blocks (collars) work well and dogs learn quickly. The main unit will beep and notify you if a cable breaks, so you don't have an unprotected area. Now the problems. The supplied cable is very thin. About as thick as a straight pin, but very soft and brittle. Yes, it breaks VERY EASILY. THE WORST thing is that there is only ONE charging cable. Yes, it is a duplex (dual) cord that will charge 2 collars at the same time or the main unit and 1 collar, but you MUST use the cord to power the main unit in either case. This means that if you place the main unit anywhere far from where you would charge the collars, you WILL STUCK. I placed the device in a secluded part of the ranch to teach dogs to stay away from one of our wildlife sanctuaries, but since the only power cord is at the shelter, I have to go upstairs and attach the collars to the cord to charge them, and then , since I'm in there, the dogs think it's time to enter the restricted area. If I loaded the collars on the manor the dogs would be with me and not exploring the reserve and spreading their scent where we don't want it. collar charging. Even if they only gave a power adapter, you could use that for the main device, and electronic collars can be charged with a standard USB charger, spare parts of which most people have lying around from several cell phones, flashlights, toys, smart tablets, and others Electronics. RATING As it stands I would give this device 3 stars if it came with enough cables. to power everything at the same time but since I have to walk 1/5 mile and enter our wildlife sanctuary to charge the collars it gets 2. I would give it 4 STARS if the wire was thicker and more durable then me would probably upgrade to a 5 star rating when i see how durable the system is over time.
