As far as the availability is concerned, the Ultima AC is only available to buy from the manufacturers website. This might be concerning to buyers who don’t feel comfortable purchasing things online and prefer going to a physical shop. However, the upside of this is that, since this isn’t available anywhere else, the chances of a person stumbling across a fake product are greatly reduced. So to answer the questions asked at the start, can the Ultima AC replace a traditional air conditioner? Well, no. This is because it is aimed at a completely different demographic which can’t quite afford to have traditional air conditioners. However, answering the second question, the Ultima AC is definitely worth buying as the price it’s available for is completely reasonable especially for what it is and what it can do. Therefore, in case you’re looking for a device to keep you cool but don’t want to spend a fortune, get the Ultima AC .
