Ollaheater Arvostelua 

AVOID.
Do NOT buy under any circumstances. The claims made violate the laws of physics.

Their very own website states the OllaHeater is 900W. To heat an "84 square metre room" from "10 to 23 degrees celsius" @ 900W is going to take at least an hour not the "minutes" claimed. It's no more energy-efficient that any other radiant or convective heater. Buy a heat pump instead.

I bought this as a senior to help manage my heating bills. From the advert it seemed a great heater with the advantage of no trailing wires. The reality is different. IT IS A COMPLETELY USELESS HEATER, and as an 80 yr old asthmatic I have more puff than the fan in this heater. It is a complete waste of money, don't buy it, keep your money.

I like many others was fooled by the fake reviews on the sales page.
The Olla Heater is little more than a small fan blowing air through a very small heating element the heating output is negligible unless you are sitting right on top of the unit . I had the heater running for almost 3 hours in a 10'x 10' room and temperature only rose by 2deg from 15C to 17C .

I have no idea it did not warm no battery for control

So annoyed at myself

Go to Trustpilot before you buy anything from the internet read the reviews most of the time it’s scam after scam if it sounds to good it’s no good

Wow Trustpilot is awesome. I too was going to buy this revolutionary heater but thought I'd see what Trustpilot had to say on the matter and so glad I did. Big thanks to Trustpilot and to the unlucky people for being kind enough to share their experiences - much appreciated

Every single electrical heater is 100% efficient. They covert 1watt of electrical energy into 1watt of heat energy. EVERY ELECTRICAL HEATER! It doesn't matter if your brought it in the 60s or if it's a brand new A rated heater. Do not be fooled by the lies in this advert. My heater also felt cheaply made.

Since I cannot find a way to get a refund on this garbage, I hope to stop anyone else from getting sucked into this scam. I was fooled, I admit it, by the commercials I kept getting on Rumble. All this product is, is cheaply made Chinese garbage, dressed up to look like an innovative product. They even come with super cheap remotes without batteries. Try to plug this into a wall socket. Does not have a third ground prong, so with the weight of the unit it just slips downwards, ready to fall right out of the outlet, onto something flammable, to burn your house down and kill you. It heats up like a stove element and at best is a serious fire hazard. Hard to believe they are allowed to import this crap. STAY AWAY!

Very disappointing! Gives off very little heat and the heater is very noisy. The advert hyped this product up to such a degree that I bought 3 of these heaters thinking I'd be able to turn my heating off. What a waste of money!
