This is the second door that we have purchased. When we moved, I couldn't live without it. It works great. We can shut it off when we leave and don't want the dogs to go out while we are gone or when it is raining and we don't want to deal with the mud. It did not take long at all to train our puppies.

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.

My dog to go out and in

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...

This has been the best purchase I have ever made! Works perfectly. Can't believe I went so many years with out having it.

Best purchase I've made in awhile! Works awesome ! My Westie loves his freeedom and we enjoy not getting up to let him in and out ! Would highly recommend!

This is an excellent product. Very easy to install in the wall especially with the tunnel attachment. It's very sturdy. A friend has had one of these for several years with few problems, which is why I chose this door. The door came with one battery operated collar which I'm quite happy with. I have a small dog about 10 pounds and this collar is the perfect size. I purchased the rechargeable collars as well but they're very bulky on the little dog.I am concerned about the customer service at High Tech Pet, however. One knob was broken off during shipping so I tried calling and emailing High Tech Pet about getting just the knob replaced but the phone number didn't work and I didn't get a response from them by email. Amazon's customer service, on the other hand, is fantastic. They offered to replace the whole door but I was hoping to hear from High Tech Pet about replacing just the knob but they never did get back to me.

THIS DOOR IS AWESOME. IT IS ALOT MORE SECURE THAN YOU NORMAL DOORS AND OTHER ELECTRONIC DOORS.THE ONLY THING THAT I WISH COULD BE DIFFERENT IS THE SPEED OF IT OPENING. SOMETIMES THE DOG NEEDS TO RUN OUT TO SCARE SOMETHING (ANIMAL,PERSON) AND THEY CANT GET OUT AS FAST AS THEY HOPED TO.
