Innotek Extra Receiver Collar for Zones Pet-Containment System, ZND-1025

I expected to receive an Innotek ZND-1025 collar as pictured and labeled.Actual product received was a lower quality replacement item (PetSafe RFA-377).Reported as "Only the name has change, the item remains the same."But, the nylon webbing is now thinner and of a lower quality, the buckle is now plastic instead of the original metal one.The circuitry in the collar 'receiver pod' seems to have changed. Does not provide audible beep at a certain distance followed by correction charge at a closer distance. Now beep and charge happen at same time and may get stronger and faster as distance to zone decreases.After a couple of emails, the seller agreed to provide refund. I did not pursue this as further investigation revealed I would probably end up getting the 'new' superseding version no matter where I purchased it.Such is the risk of buying things sight unseen from the inter-web. Ho-Hum.

I have a lab that loves the garbage and this stopped her from throwing it all over the floor, but I have to get a new collar every six months because they stop working even when I replace the batteries.

I have several of the units stashed around the house. They are somewhat effective. Sure, the dog stays out of the laundry room where the cat's food lives. But, in the kitchen, he understands that if you run and grab, you can avoid most of the shock. so, food that falls off of the counter or quickly getting things off of the counter are effective for him. Also, I am on the third receiver collar. When the batteries go out and are replaced, the collar dies. I have tried resetting it (you do this with the large donut unit) to no avail.I would give it more stars if there were a setting to deliver the whole shock without the ramp up. Beep for 2 seconds and then, BAM. It would be more effective for our superbeagle.

The zones work great, within the limits listed below.Good Points1. Has a A, B, and AB setting which lets you control individual dog access to areas or objects (such as separate food bowls for special diets, rooms, etc)2. The shock is mild but definitely uncomfortable (I tested it on me before I used it on the dogs). It is milder than the strong static shocks I regularly get around the house.3. The dogs quickly learn to avoid things that cause shocks.Limits1. Collar wear is recommended to be limited to 12 hours due to rubbing by the stud on the neck. This can be a problem with intelligent dog and schedules requiring longer wear times. Intelligent dogs can quickly learn that the collar is the source of the shock and can wait until they are not wearing it to get into the forbidden.2. The range increments listed (2-12 ft) are not dependable. I find mine, with direct line of sight, is half that or less.3. The six available range settings are not enough. There are times that 1 or 2 ft increment is too much.4. Area of affect is spherical. Keep this in mind when deciding where to use them. Depending on the range setting, just walking by the counter or under the table can set them off even if all you intended was to discourage Fluffy's nose from appearing on the counter/table top. The only way to alleviate this is to find some way to dangle the zone from the ceiling to correctly limit the reaction area to those 3 ft off the floor.

This collar is part of an excellent containment system which I had installed over a year ago. This system is perfect for the standard home.

THis product worked great to keep our cats from going onto the second floor of our home! Made us happier cat owners.
