High Tech Pet Fully Automatic Pet Door for Wall and Door Installation - Large (PX-2DM, Large Door Mount)

This product has been amazing so far. I expected the best at this price point and I was definitely not let down.Installation - With a hole saw and a jig saw you can get this done pretty quick. I think it took my neighbor and I about an hour and a half to install this and we did this with the door still in the frame.I took the outside piece (the smaller one) and centered it so the bottom of the opening was pretty close to my smallest dogs arm pit, put a level on it and traced it out. Used a hole saw for a starter hole for the jig saw (make a couple holes) and cut out the square. Once cut out I used a white waterproof silicone to add an extra barrier of sealant on the inside and outside pieces, this will also help with holding this in place as I have one of those really weird "Thermal" doors where its basically made of PVC and filled with foam so the screws only have about 1/4 inch of PVC to hold onto.Use - I have a Maltese (Dexter) and a Westie (Spencer), Dexter is a very skiddish dog and did not like to at first, the opening and closing of the door freaked him out and he would run away. There is a manual open button so I would press that and walk outside with a treat and no joke within 1 day they would use the door to go outside with me standing there and asking if they wanted to go outside. (I am still on day 2 of the door so I am not sure if they use it when I am not there but every time I ask if they want to go outside they use the doggy door and come back in) I will update in a week or so.Quality - You get what you pay for, its a great door. There are control knobs for each sensor so I have the inside sensor set a little lower so they have to be within 2-3 ft of it and the outside one bumped up like 2 notches so it opens once they get on the patio within 4-5 ft of it.Recommendations - I would highly recommend getting the battery for it, I am ordering one after I leave this review. It plugs in so if the power goes out your dogs cant go outside without you home.Security - The hole itself on the size I got is pretty small, a child would have a hard time getting through the hole let alone an adult or midget. The collars are "plug and play" so anyone with this type of dog collar could get it open but lets be honest, chances are slim someone would have the collar on them and even if they did the hole is super small they would probably use another point of entry... There are also buttons to enable or disable sensors so you can disable the sensors at night time if the dogs sleep with you if you are worried about security concerns.Overall - The product is great, I would just recommend having treats on hand and ONLY allowing your pets to use the new doggy door to go outside for a few days, once they get used to it the quality of life for your pet will go through the roof. Just like us they can decide to relieve themselves when they want to.EDIT : The collars come with enough "Strap" to fit on any size dog, once you install it, cut it to the desired length and then take a lighter to the frayed edge and squish it with your finger tips to keep it from fraying and pulling apart like a sweater...

I purchased this tentatively as the price was not low. However, the item is well made, functions beautifully and looks good on the door. It is not noisy and we installed it our master bathroom door which leads to our patio/backyard. The range sensitivity can be adjusted easily and the door closure wait time can be adjusted as well. We started out letting the door open when she got 4 feet near it then adjusted down to about two feet after a day. The dog figured it out in one day. Did a very short training session for about 15 min. When the door is down it is solid and will not let anything in that does not have the radio collar on. Installation was relatively easy. I am not a big fan of the cord but I since I love the door I will be purchasing the back up battery for it.

We purchased this for our two cocker spaniels and it works great. It has been installed for a few weeks now and they use it regularly. We installed it in a metal exterior door that has a window. We had to get the large size so the top covers part of the window, but we don't normally open the window in this door anyways. The installation instructions are not great, but we are handy folks and did not have any problems with the install. Took the door off, marked the measurements, drilled holes in the four corners and used a jigzaw with a good metal blade to cut through the door. Had to cut both sides. One the hole was in place, the unit installed very quickly and easily. We had a power outlet right by the door, so we went with the AC plug that comes with the unit. I really like that the door allows for the plug to be connected on either side.The dog collars are small and don't seem to bother our dogs at all. The unit comes with one collar and we purchased a 2nd on Amazon also. One minor challenge we have is that if the collar spins at all, the sensor won't line up and the door may not open when the dog walks up to it. We are playing with the sensor adjustments now to see if there is an impact. It confuses the dog when the door won't open, but fortunately, since we have two and they are usually together. The other one will walk up or come back in from outside and open the door.The unit does not have an adjustment to specify how long the door should stay open once they walk through it. Since we have two dogs, this would be great. I didn't take any stars off for this though because we still really like how it works as-is.We haven't recognized how long the collar batteries last yet. They are specialty batteries and are not cheap, but we understand why... to keep the sensor small.We definitely recommend this unit. We had a hard time determining what size to purchase. Our dogs are fairly small. One weights just over 30 pounds, which was the max for the smaller unit. We did some testing with cardboard and determined that the larger unit would be best for our dogs, even though they are small. The size is great. They have plenty of room to run through the door and it is not too large. Sometimes they try to go through it together :-) .We did a lot of research on all the options available and from what we've reviewed and now what we've experiences... we are very confident that we made the right decision.
