Tim Visser and James Chisholm each scored twice as Harlequins began their European Challenge Cup campaign with a comfortable 43-21 win over Stade Francais.
Quins were beaten 26-19 by Montpellier in last year's final, but made an early statement of intent at The Stoop in their quest to go one better this time around.
And it was Scotland wing Visser and number eight Chisholm who did the majority of the damage as the hosts built a 36-7 lead, with Stade missing out on a bonus point despite an improved second-half showing.
Joe Marler crossed for the opening try from a maul, Tim Swiel adding the extras before Joe Marchant made it 12-0.
Visser then went over for his first score after he broke from his own half and exchanged passes with Mike Brown, with Swiel's conversion making it 19-0 just over 20 minutes into the contest.
Sekou Macalou trimmed the deficit by capitalising on a sliced kick from Marland Yarde, only for Chisholm to leave the visitors with a mountain to climb following a quick-fire brace.
Man of the match Chisholm powered through some poor Stade defending to go over on the left flank and crossed in the other corner on the stroke of half-time as he surged down the blind side from a ruck to make it 31-7.
Not to be outdone, Visser scored his second try in spectacular fashion in the 58th minute, intercepting as Stade attacked from a scrum and going 95 metres the other way - though Ruaridh Jackson's conversion attempt from in front of the posts was charged down.
The French side threatened to take at least one bonus point as tries from Clement Daguin and Willem Alberts put Stade within 15 points.
But they were unable to find the fourth try needed to avoid going home empty handed and Yarde's late score rounded off an excellent Quins performance.
