A third remarked: "Estonia’s magic vanishing and re-appearing guitar was the real star of the show tbh #Eurovision #EurovisionSongContest."
Earlier host Israel's act Kobi Marimi sparked controversy with viewers tonight as he burst into tears after his performance.

But some viewers lashed out and accused him of "fake crying" to get votes.
One tweeted: "Your man from Israel there really should have put a little time in to practicing his fake crying... #Eurovision."
Another remarked: "Ah, there it is, Israel. The fake/ugly crying #Eurovision."

Eurovision fans brutally blast Czech Republic's 'worst drum miming ever'
The Czech Republic's Lake Malawi stunned viewers with, what they branded, "the worst drum miming ever".
Czech Republic's Lake Malawi also failed to impress Graham Norton, who wryly remarked that their song Friend of a Friend was "borderline annoying".
Fans took to Twitter to joke about the incredibly awkward miming of the drummer, who wasn't exactly in time with the beats of his own drum.
One tweeted: "Possibly the worst display of drum miming EVER from the Czech Republic lads forgiven for there youthful good looks! #eurovision."
While another commented: "Definitely questionable lyrics but you just know this is going to be stuck in your head all night. Also, miming playing the drums #CZE #Eurovision."
Eurovision 2019 odds: Netherlands are favourite to win - but odds are dire for UK
A third remarked: "Out of sync drum miming ftw! #CzechRepublic #Eurovision."
"Lol at that drum miming #Eurovision #CZE," another wrote.
The poor Czech drummer wasn't the only act accused of miming tonight.
2019 kickstarted with an explosive opening number which included a plane delivering all of this year's contestants.
But some viewers felt the high-energy opening was marred by the miming of its former winners.
This included Dana International, who won the competition in 1998, and Netta Barzilai, who rose to victory last year with song Toy.
While some fans were happy to see the former champions, others flocked to hit out at the dodgy miming.
One tweeted: "That is some terrible miming, Dana #Eurovision."
While another commented: "Worse miming than Steps #Eurovision."
A third remarked: "Is Netta miming her speaking? #Eurovision."
Dutch act Duncan Laurence is the bookies' favourite to win the competition tonight ever since his single Arcade was released.
The Netherlands hasn't won the competition for 44 years since Teach-In in 1975, previously taking home the trophy in 1957 and 1959.
Australia are the second favourites to win, with their odds dropping slightly after their staging was revealed in the first semi-final.
Meanwhile Ireland, who holds the best track record for Eurovision victories with seven trophies to their name, crashed out in the second semi-final last week .
