High Tech Pet Genuine MS-5® Automatic Smart Pet Door Collar, Tested & Certified for All Power Pet Doors - Water Proof, Battery Included, Complies with Power Pet Door Performance Warranty

Works great, but it’s worth getting the plastic protector for it. And don’t put the screws in too tight. It breaks the cover plate super easy.

My golden retriever had her Collar on and splashed in the river. It was not submerged and it stopped working. Had it only for 25 days and the company replaced it. My other dog has had hers for three months and no issues. It works great with their electronic dog door and the dogs love it as they could go in and out to the backyard as they please

Absolutely the best ever. We have had an electric doggy door for 8 yrs and these collars are amazing.

These work good, however they are not waterproof. They can withstand some water but will stop working if left in water for too long. I have two dogs. Ozzy will jump in the pool and jump back out. His collar has never had an issue. Willow likes to stand in the water for several minutes. I dont have the collars super tight so they tend to fall to the bottom of their necks which then puts the sensor in the water. I’m on the 3rd collar with Willow. I’m assuming that they shorted out due to the water. I used my food saver to make an airtight pouch for the collars, and haven’t had an issue for since. I returned the first shorted out one through Amazon. The 2nd one, I contacted customer service and they immediately sent a replacement. My Scottie’s are now happy that they can go in and out whenever they want. Which makes me happy and not frustrated having to get up 20 times in the evening.

I was using the MS-4 collars for our Power Pet Medium Electronic Pet Door PX-1. We had issues with dirt, hair, and water getting inside the collar causing it to stop transmitting. When one of the MS-4 collars broke, I decided to try the MS-5. Here are my thoughts: 1- this is the type of collar all units should come with by default. 2- the enclosure is secured by a small screw which is much more secure than the MS-4 plastic clamshell. 3 - this type of collar is more expensive up front, but it makes it easier to use generic batteries instead of the High Tech Pet batteries which are severely overpriced. See details below on how to do this. To save a lot of money on batteries, follow these steps to use generic batteries instead. This will take <5 mins once you've done it once, so don't be scared of the steps: Step 1: Buy CR2430 batteries (any brand will be fine) Step 2: On a dead High Tech Pet battery, take note of the two sides - One side has a donut shaped white sticker under some foil, and the other side has a circular white sticker. You will need to be careful in the following steps but it is easy. Make sure you keep track of which way the battery is oriented so you can replace your generic battery properly. Step 3: Peel the circular sticker off without ripping it. Under the sticker you can see two foil tabs welded to the battery. Using an exacto-knife (or something similar) carefully pop the tabs off of the battery without ripping or cutting them. They should come off as one dented looking tab. Step 4: Now that the tabs are popped off, remove the foil donut and underlying sticker as one piece (again without ripping it). You should now have three separate parts: the foil donut with foil ring combined, the battery, and the top circle sticker. Step 5: Replace the battery with a new one: Make sure you place the foil donut on the battery in the right orientation. Now that the battery is loosely placed inside of the donut, fold the tabs back down onto the back of the battery. These seem very loose, but you will fix that later. Step 6: Place the circular sticker over the tabs. Step 7: In order to make sure the tabs stay "squished" down to the battery, I used a thin piece of cardboard. Cut a circle the same size as the circular sticker out of a piece of cardboard. You will sandwich this cardboard on top of the battery when you do the final install in the collar. Step 8: Place the battery back into the collar, with the donut facing down onto the springs. Step 9: Place your cardboard circle on top of the battery's solid circle sticker. Step 10: Close the back of the case. If your cardboard is too thick you wont be able to close it properly. I like the MS-5 collars because they use a screw instead of a clip to stay closed, but this works with both MS-4 and MS-5 collars. Congratulations - you just saved tons of money of the lifetime of your door. Especially with 3+ animals...

Details: Purchased - 2013 Model: PX2- Large Dogs: Doberman (dog breed should definitely be taken into consideration for wear and tear potential) Story: I dont write many reviews, but I have come to a boiling point with High Tech. Reader be warned. I will try to be as neutral as I can. Door has an over all good construction and works for its purpose. Up, down, locks. Easy enough? Over my now four year span with this door i have done the following: Replaced the bolts that hold in the door with larder more heavy duty to have a better seal and strengthened the door significantly. I had to do this after a power outage and the battery backup i had purchased failed (bad battery from high tech) My 80 pound lean dobby decided he didnt want to stay outside in the rain to he kept jumping on the door till the dog door backing busted off. He then dried himself off on the couch after coming in. Door bolts replaced and that issue is no more. Kicking the door in would be a challenge after that. Bad /Mixed parts: Iv had to replace several parts on this door. Motor 2x, sensors 3x, and main board 2x (once due to new motor not being compatible with the old one, via high tech diagnosed that) This is war and tear damage from having dogs CONSTANTLY in and out. I can let that slide on the review rating. "is what it is" cost Sensors: Sensors are horrid. Iv since day one had to keep the sensors on MAX for the door to open 12 inches from the opening. Same from outside. Otherwise the door when they are smack dab in front of it would not open. So after a few years of doing this and some extra parts I added in a second sensor and mounted it on the side. Totally fixed the range issue by adding a new LOS (line of sight) Collars: Ok so now comes the hate speech. Im NINE collars deep at this point. Yep, NINE. 9. 09. 1,2,3,4,5,6,7,8,9. I have doberman. They run, jump, rough play with each other, and so on. These collars break like the cheap plastic they are. Now due to my own collar modifications the last 3 have lasted 4 times longer then the rest. Modification: I take the collars and wrap them in Silicone Rubber Self Fusing Tape around all the edges and the middle. I then I take an exacto knife and cut out the silver sensor, test button, and led light. This then gets attached with zip ties to their collars. As you can see this becomes a PAIN in the ass when you need to change the battery. Inevitably the collar breaks or stops working over time. High Tech PLEASE FOR THE LOVE OF DOG GET YOUR COLLAR FIXED. You say on your website: "Plexidor's biggest drawback is its price, a whopping $1200.00! We have no idea why it costs so much or why anyone would spend this kind of money when the Power Pet door, at 1/3 the price, performs so much better, looks so much better and gives you so many more features." Iv seen the reviews for that door and they dont seem to have near as much replacement cost issues as this product. I have my parents and two friends that have purchased this products and we all have the same issue. The collars are total crap in the current configuration. Had i known my "1/3ed price door" was going to cost me over 1000 in maintenance costs to keep the system going I would have never bought this system that now my dogs depend on. It would be awesome to talk to some "engineers" and get this product where it should be. Again now i have to order another collar so 50 down the drain.

I can't give this anything but 5 star because it has made things so convenient for me ... doggie door is down stairs and all I have to do now is tell her to go outside... and door opens for her. I don't have to worry about other animals coming in. She has worn it constantly for a few months now with no problems - and she is somewhat active. The other day, we went to the lake and I forgot she had it on. She got it wet but it is working fine this morning. The batteries are very expensive, but if you are looking for convenience, it is totally worth it.

These are not durable enough. I have 4 dogs and have had to buy 11 of them over the course of 3 years. Make the attachment point for the lid out of aluminum with a removable loop of different sizes for different sized collars. Dip the entire chipset into a protective coating to avoid water damage. Make it easy to swap out the tiny speaker with a replacement in case of pitch failure. I have some that work but are probably slightly off pitch and do not get recognized by the unit. I wish it used a more common battery that is rechargeable AAA instead of a flat one. Cool piece of tech but it needs some improvement for the price I’m paying not to train dogs to use something else. If you have any kind of budget or ability to train your dog to do something else there is no reason to get this at all because it’s simply a money pit.
