Before I got this, I was always worried about my car's battery dying unexpectedly, especially during family trips with my child. Now, with this device, I can see exactly how the battery is doing, and it automatically manages the power between two batteries, which has saved me from a few potential headaches. It seems to protect against common issues like overcharging, and the build quality feels solid, though the warmth it generates is something I'm keeping an eye on. Overall, it's made my driving experience much more reliable, and I appreciate the practical benefits it offers for vehicle maintenance.
- Pros: I was very impressed with how easy it was to set up; it came with all the necessary parts, so I didn't have to fuss around much. The display screen shows clear information about my battery's condition, which helps me avoid any surprises. It feels sturdy and handles rough weather well, giving me peace of mind on long drives.
- Cons: It gets warm during use, which makes me a bit nervous about its long-term durability, especially in hot conditions. The installation, while straightforward, still required some basic knowledge that might not be ideal for complete beginners. I wish it had a bit more guidance for someone like me who isn't very tech-savvy.

I got this as a gift for my husband who's always tinkering with his truck, and my first impression is that it does what it promises. The screen is a nice touch, showing the battery status without any fuss, and it seems to handle the power demands without issues. It was easy to set up, which is a plus since neither of us are experts, but it took some effort to mount because of its size. After using it for a short while, it's held up well in the Texas heat and rain, no problems so far. Very reliable for keeping the batteries in check, though I'm a bit skeptical about the long-term durability, but for now, it's doing its job well. Would recommend with some reservations, but it's a solid choice if you need something like this.
- Pros: The screen shows battery health clearly, no guessing needed. It handles power well, keeping everything charged properly. Installation was straightforward with all parts included, and it feels very durable in tough conditions.
- Cons: Most likely, it's a bit bulky and heavy, which made fitting it in tight spaces a challenge. The price felt a bit high for what it does, and I wish it had more customization options for different setups.

before i got this isolator i was constantly worried about my battery dying on me during long trips it was a real pain :( now after installing it i feel so much more secure the LCD screen tells me exactly what's going on and the isolator does its job without any fuss it's been a lifesaver for my DIY projects and weekend getaways the only hiccup was the wait for delivery and the initial cost but as it seemed to me it's worth every penny for the convenience and reliability it brings to my setup
- Pros: the isolator was incredibly easy to install everything needed was in the box :); the LCD screen is a game changer no more guessing about battery health; it works flawlessly with my 12V system and the built-in protections give me peace of mind; the build quality feels solid like it can handle rough conditions
- Cons: delivery delayed a bit which was frustrating; the price seemed a bit high for my budget but i took the plunge; the instructions could be clearer for someone not as tech-savvy; the screen is great but i wish it was a bit brighter for daytime viewing
