Horrible product and app. ### 1/5 — Garbage for anything other then charging *2019-09-09, version 1.4.8* I bought this for the find car feature vs a regular charger plug nothing works besides the color change and the charger it’s self this app is horrible DO NOT DOWNLOAD and if u purchased this and haven’t opened it and planned on using the feature return it and save your self some money and just get a plain charger ### 1/5 — CHINESE CRAP APP *2019-08-30, version 1.4.8* Doesn’t work. Cheap color change bs that doesn’t work with the app as stated...and it’s sold at Walmart, the warehouse of cheap Chinese crap. Deleting app and taking the plug back to Walmart. You dam Chinese won’t get my money anymore. ### 1/5 — Chinese spyware *2019-04-01, version 1.4.8* App does not perform core function of changing LED color. As soon as unit powers off it returns to multicolor fade effect. Why does this app for a cigarette lighter charger need Bluetooth comm with constant location services and notification privileges? Absurd. ### 1/5 — CRAP APP *2019-01-13, version 1.4.8* App doesn’t work for crap, you set he color you want, but once you confirm it changes back to out of box settings. Can’t locate your car cause it won’t connect to Bluetooth. Only thing that works is battery voltage. ### 1/5 — Disappointed *2019-01-06, version 1.4.8* The ideal of this product would be great, however, it will only connect 4 of my songs, and doesn’t show any instructions on how to actually use. This is one of those products the Chinese you to track ya with. At least that’s what I’m beginning to think!!! ### 1/5 — Don’t Purchase! *2018-11-18, version 1.4.8* It would not connect to my bluetooth, I tried everything!! ## Most critical reviews (10 lowest-rated) ### 1/5 — DO NOT BUY THIS SPY GEAR *2025-09-19, version 1.4.9* I bought this adapter to play music in my car it didn’t even work the app won’t work without your location either seems really strange to me if you bought this charger don’t even download this app go return the adapter ### 1/5 — Why is my phone vibrating? *2025-05-18, version 1.4.9* I downloaded the app did everything it said to do and ten seconds later my phone started vibrating. Prior to this I was telling my sister the Chinese were going to steal my info and explode my phone. ### 1/5 — TRASH PRODUCT AND APP LOOK AT REVIEWS BEFORE USING *2023-03-16, version 1.4.9* I bought this transmitter for 10 dollars… nothing worked except the lights rlly was a waste of money and time. Don’t recommend ever buying anything like this again. ### 1/5 — Don’t download *2023-02-20, version 1.4.9* The app doesn’t let you to connect to any sort of music app and doesn’t let you play anything. I tried to play music on Spotify on my truck and the app didn’t let me do anything so did the so called smart charger don’t buy ### 1/5 — **CONFIRMED SPYING** *2023-01-19, version 1.4.9* DO NOT download this app or buy this Chinese SPY GEAR. Pretty unforgettable experience, after reading other reviews about it being an opportunity for spying, my girlfriend and I laughed about it. She jokingly typed into Google translate things like “I know you’re listening Chinese spy”, she translated it to Chinese and played the audio right next to the charger. Seconds later a male Chinese voice started speaking through my cars speakers!!! My phone was not plugged in and it was heard by both of us!!! We checked if there was any other factor that might have played audio and there was no way. I know it sounds nuts and I don’t know how it’s possible, but I’m pretty creeped out nonetheless. First review I’ve ever made on an app. Nothing else to say besides I’m returning the thing tomorrow morning. ### 1/5 — DO NOT BUY! *2023-01-10, version 1.4.9* I bought this for the Bluetooth specifically and it doesn’t work! It makes you play music through the app and it cost money for the app it coworks with. It’s absolutely trash! ### 1/5 — 👎🏻 *2022-10-27, version 1.4.9* this app and its product are of poor quality ### 1/5 — Tried stealing my passwords *2022-08-19, version 1.4.9* Got a notification saying my data was leaked don’t download horrible product ### 1/5 — Don’t buy it *2021-09-27, version 1.4.9* Absolutely useless. Other than charging, it’s not a good product you would like to have in your vehicle. ### 1/5 — TERRIBLE APP and PRODUCT *2021-07-27, version 1.4.9* It barely works the music won’t work at all it’s ridiculous don’t waste money or time ## Most praised reviews (3 highest-rated) ### 5/5 — Smart 12V+ *2024-03-18, version 1.4.9* I baught this device from Walmart for 10$ hasn’t worked since I’ve had it. Don’t buy this item. ### 3/5 — Not playing music *2021-04-05, version 1.4.9* The instructions weren’t clear , how do I play music ? Bluetooth connected , everything is turned on yet music will not play. Any help ? ### 2/5 — Only choose color *2020-08-18, version 1.4.8* The app is only capable of selecting a color for your light. Don’t allow location. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
