Reviews are on the Reviews tab of any DJ's profile, with their Average rating and Total reviews.
Who can leave one
Only a client who booked that DJ through DJfindr and whose event completed. The profile says so: only verified clients that booked and completed their event on DJfindr can post a review.
That rules out reviews from friends, from enquiries that never became bookings, and from events arranged elsewhere. Every review you're reading came from someone who paid this DJ and had them play.
What each review shows
A star rating, the occasion, the review text, and the reviewer's first name and date.
The occasion matters. A run of five-star reviews from nightclub bookings tells you less if you're planning a wedding.
Reading them well
Look at the occasions first. Has this DJ actually done events like yours? A great club DJ may never have handled a wedding timeline.
Read the text, not just the stars. Specific reviews are the useful ones. "Kept a mixed-age crowd on the floor all night and handled the speeches running late" tells you something. "Great, thanks" doesn't.
Look at what a critical review is about. Communication problems tend to repeat. A one-off complaint about a venue's noise limit doesn't.
Weigh volume against average. Forty reviews at 4.6 is a stronger signal than three at 5.0.
Check the pattern, not the extremes. Every busy DJ eventually gets one unhappy client.
What you won't see
Reviews can't be edited or deleted by the DJ, and there's no reply. What's there is what clients said.
A newer profile
Few reviews isn't a red flag by itself. A DJ may have years of experience elsewhere and be new to the platform. Weigh their mixes, their posts, and how they answer your first message more heavily.
Reviews are one-way
Clients review DJs. DJs don't review clients.
Leaving your own
After your event, you'll be asked for one. It's the main way the next client judges a DJ — see Leaving a Review.
