If you have 155mm between holes and access to the underneath of the holes, then look no further, this is a great seat at a reasonable price.
Good:
Fixed hole spacing = no adjustment mechanism to loosen off and make the seat wobbly
Soft close = no more seat banging
Easy remove = easy to clean right underneath the hinges
I recently got fed up with not having a soft close seat in the en-suite. The others in the house are soft close, so I'd forget and it would slam down.
Replaced it with one of these, and it's so much better.
The adjustable gap seats, all use a similar mechanism that over time go loose (body weight + leverage overcomes the rubber washers).
This fixed distance (155mm) fitting is much easier and is rock solid.
The downstairs one is being replaced next, as it gone wobbly...
Remove the old seat, put the plastic bolts firmly in the fittings, put in place, use a 16mm spanner/socket to do up the bottom fixers, and when the sheer nuts break off it's tight enough.
Took longer to get the old one off, than to fit the new one!
