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.
I am in Australia. I purchased a filtered coffee machine (this is the coffee that drips into a pot on a hot plate) so it's all really a heading element. It was a US machine, so 110W, and I really liked it. Using a standard, cheap US-Australia converter caused my first machine to die after the second use because we use 240W here and it basically fried the heating element system as expected.
Electronic shops here sell very large and expensive "step down" converters for my purpose, but this plug did exactly what I wanted. Read the instructions, you need to turn on the step-down system on the plug which is a separate switch. In any event, used it many times and works perfectly. Cost effective. Should be suitable for other things like irons or electronics involving heating elements requiring 110W US power supply.
When the Australian plug clicked on, it doesn't always fit particularly well into power points here due to the bulk often extending over the switch. But if you put a double adapter into the wall before this plug, it works perfectly fine. Recommended for those who need step-down. Works great as a travel plug converter as well.
Quality construction and materials, however doesn't sit flush on Australian switch plates due to location of switches above and above right of the socket. Unfortunately appears to work everywhere except Aus/NZ
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)
I bought this product to use primarily for travel to Asia. The size is very convenient for travel. The only thing to keep in mind is that the product isn’t recommended for use for things like appliances but the seller is very responsive if you have questions about use. Working as expected and I don’t have any complaints.
