Updating my review back to 5 Stars. The company has reached out to me and addressed my concerns and my problems with their product. They have professionally replaced and handled my problem with their product with care and concern. I am a regular customer whom purchased multiple of these packs that in some case were defective however when I had submitted a complaint they had addressed it and replaced my order immediately. I had received the product literally 2 days later. I have bought over 30 different portable chargers over the past year and alot of these brands were either generic or mediocre. But this brand I really like Alot Hence why I bought almost several orders of specially ViyiSi brands. I bought this brand specially for how fast, durable, convenient these battery packs were. I am very pleased for this companies service and they offered to replace future battery Packs that may become faulty. This is my favorite brand. Read more

This is a game changer in our house. As long as you return the Four charges to their base station every day, you have Four ready to go charges at all times without the panic of having to remember to plug them in like with other charges. They fit neatly into the back of the iPhone And give a good extra charge. We did have a problem with one of the charges where the input was loose but the product was changed immediately. Very happy with this. Good product Read more
