"Checked in shop and it seemed reasonably accurate both horizontal and vertical. Cheap construction so I would advise checking that it is suitable for your needs when you pick it up (I doubt that they are all accurate and you may get a bad one). Have used it on scaffolding and it worked fine, magnets held it in place. Manufacturer might consider putting a v groove in the base to help get it straight on a pipe."
"Works as well as my £30 stabilla. Got this as a backup for my site bag and think its worth every penny. Only downside is the plastic around the bubbles could be better quality as one is chipped after the first day"
"Checked this level against a larger level that I know to be true prior to use. The first thing I noticed was that this one gave a different reading if placed down one way and then rotated through 180 degrees. Returned it to Screwfix for another one of the same. Checked in store and it turned out to be even worse! Exchanged it for a Forge Steel one at the same price which was spot on. Item 5014C"
