To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
they write in the title "Step Down 220V to 110V for Electric Product Like Hair Dryer Steam Iron Cell Phone Laptop MacBook" which makes you think that it is a voltage converter that can be used on 110v- only consumer electronics and it's simply not true. This is on the verge of a scam.
If you have a product with a 100-240V rating, then you only need a mechanical adapter and this is the wrong product, as it is way too expensive for this need. there are adapters that cost 10th of its price. If you want a voltage converter for a 110V- only, then this is also a bad product since it is unusable for most of the products. Only usable for hair drier and a selected few negligible use cases. They write it explicitly, but not clearly enough, and they advertise it as a converter, which is clearly not. So they deserver the bad rating.
This item arrived late. The packaging was good. When we tried it on the converter switch it was not working. You can use it as an adaptor as it has ports for different outlets, though if you just need an adapter purchase something smaller.
I would not recommend this product based on quality (meaning the converter aspect not working- which is why we purchased it)
