And for ppl not going to Helsinki Area, the fix taxi rate doesn't apply and things are more complicated. I got very different prices for the same address in Espoo for the last few times(difference larger than 10€, some deviates almost 20eu). And they are from those Fixu/Menave companies.... Even though I could tell there was scam, nothing I could prove. They all seem charged me directly from meter and I don't know why price could be so wrong(I should had have paid more attention from starting price, maybe) I have knowledge of the correct range of price, because I also order taxi to HEL from the same address, and those prices are pretty consistent.

Taxi from HEL used to be quite reliable before Covid, at that time no company taxi line I just took whoever comes first, and never had any big price deviation. In general I trust company "taksi Helsinki" and I got instant order from its call center. ( Edit, they are also on Line2 from airport)

Just really, be cautious...and maybe order taxi(Uber) is the best way to avoid scam.
