Snap resistance is the property that gets tested in practice · review
Three keyed-alike cylinders in solid brass with a matt nickel finish, and fifteen keys between them. GERCAR states stock keying, which is what makes a three-cylinder set affordable, and supplies both 50 and 80 mm (3.15 in) fixing screws.
The conclusion The only set here that gives one key for three doors, with the caveat that stock keying is not unique to you. Sensible on outbuildings, thin on a main door.
A house frequently ends up with three cylinders and three keys: the front door, the back door, and the garage or side gate. This set makes them one key for the price of one decent cylinder.
Stock keying. The cylinders are pre-cut to one of a limited number of factory combinations rather than to a code unique to you, which is why a three-set costs what it does. The consequence follows directly: somebody else who bought the same batch has a key that fits.
For a garage, a shed and a side gate, that is a reasonable trade — those doors are protected by being unremarkable, not by key uniqueness. On a main front door it is a real objection, and a cylinder from a maker who states a standard is the better place for that door.
Brass rather than alloy: heavier, corrosion-resistant, conventional. And two lengths of fixing screw in the box — 50 and 80 mm (3.15 in) — which sounds trivial and is the difference between finishing the job and driving to a hardware shop with the door open.
One key for three doors means one lost key affects three doors. Decide that deliberately, keep a spare off the premises, and think about which doors genuinely need to share.
Outbuildings, gates and secondary doors. Put a better cylinder on the front.

It means the cylinders come pre-keyed from a limited set of factory combinations rather than cut to a code unique to you. It is what makes a keyed-alike set this cheap, and it does mean somebody else's identical set opens yours. For a garage, a shed and a side gate that is usually acceptable; for a front door on a main lock, it is a reason to spend more.
Because the cylinder fixing screw has to pass through the door and reach the cylinder, and doors vary. Sets supplied with only one length are the reason people end up at a hardware shop mid-installation. Two lengths in the box is a small, real convenience.
Heavier, more resistant to corrosion in most environments, and traditionally what cylinders were made of. Alloys like Titalium have their own advantages, particularly in salt air. Neither is a security grade: EN 1303 sets one. GERCAR says it meets class 2 “in essential points”, citing no certificate; the BASI V55 pair in this hub states the standard without that caveat.
