LASTBUS WiFi Magnetic Hitch Wireless Backup Rear/Front View Camera Rechargeable Battery for Easy Hitching of Gooseneck Horse Boat Travel Trailer/Fifth Wheels/RV/Camper Reverse for iPhone iPad Android

Product works great for connecting my gooseneck trailer to the ball in the bed of my truck. Magnetic amount is very strong, excellent design. Location of antenna is awkward because it does not allow the camera to be completely horizontal. It would have been a better design to place the antenna so that it did not limit this. I have found however that I do not need to use the antenna in the bed of my truck because it is not very far from me in the truck cab. If I were to use this on the back of a trailer, which I have not tried yet, I would likely have to use the antenna but I don't think the limitations that the antenna put on it in terms of camera rotation would be a problem. I would recommend this product. Excellent price.

(Update after one year: It's been consistently reliable and has good near focus to see the trailer hitch position clearly when reversing with the camera on the hitch bar. Needs the aerial connection to connect when at the back of a 25' trailer. Holds a charge well and never a problem connecting to an iPhone. The price has gone up considerably but still a good choice as a versatile and useful device.)Very helpful for reversing and hitching a trailer. The magnet holds firm but it's easy to slide the camera off. No problem doing the wireless connect to an iPhone, which is a problem I've found with other devices. The app is perfect for - not fussy and you can easily put a reverse guideframe into the image, flip the picture L/R or take a selfie if you're so inclined. Picture quality is not great but it's fine for the purpose intended. My only problem has been with the wifi connect at the full length of the truck + trailer (it drops) but that's with the camera by itself - there's an aerial extension that I've yet to try that will almost certainly resolve the issue. Overall good value for the job intended, and a LOT less expense and fuss than other options.

Great product, very simple to use:1. Turn on camera and cellphone or tablet2. Snap camera onto bumper (very strong magnet) or other steel surface such as water heater cover3. Turn on wifi in camera4. Open up camera's SWD appThat's it- no issues with intermittent signal or battery's life5 star

Need to know!If during setup you deny access to your location, it will not show video.I cannot imagine why this system needs to know my location in order to function. Setup otherwise was fairly simple and easy.I find the angle of tilt to be limited, and wish it had a bit more.The first photo shows the camera on the tailgate and the full angle of tilt in that position. It will not go to a more horizontal position.The second photo shows the view from the tailgate location.The third photo shows camera on the step of the bumper.The fourth photo shows the view from that location.On the step of the bumper, I could see further aft, but it was not easy to tell when the ball was directly under the receptacle.On the tailgate I felt I had a better sense of vertical alignment, but the view aft was limited in range, so I was looking out the back window until there was less than 10 ft between the ball and the tongue, before I could see the tongue.I would suggest that if you cannot see the trailer out your back window, start with the camera on the step of the bumper, then move it to the tailgate.On my 2001 Toyota Tundra, the bumper has a plastic cap, so the magnet doesn't hold very well there, but on the tailgate it holds really strong. I wouldn't worry about it falling off the tailgate on the expressway, but I wouldn't leave it on the step of the bumper even in my yard.Range without the antenna is just past the front bumper of my truck, with the antenna is about 40ft.All in all, I think it is a worthwhile expense if you pull a trailer regularly.EDIT: Due to the very wide angle of the lense, it is very difficult to estimate the distance of objects or obstructions that are more than 10 feet away from the camera.

All in all I am very happy with this. I got this for our 2 old farm trucks. We regularly attach trailers to the bumper or as a gooseneck, and this makes it so much easier!Also, I have an android phone. I don't know if it matters, but you download a different app for IOS than Android. Have not tried it with my daughters' iPhones yet.Pros:The magnets are super strong, but not so strong that you can't get it off again.The picture is clear and I have not seen any lag.I have not tested max range, but it sure works from the truck cab to the rear gate.It is super easy to set up.Cons:You have to manually select it under the phone's Wi-Fi settings each time you use it as the app will not do that for you for some reason.The indicator lights for charging, power, etc. are super tiny and dim. Not a huge deal, but baffling in todays world of bright LEDs.
