Utoolmart 10pcs Bubble Level, 9.5×34mm Mini Universal Spirit Levels Bubble for Picture Hanging, Measuring Instruments Layout Tools

very quick service , could have have a smaller pack. only needed 3 , keep for spares

Good value. Fitted my spirit level - original components had clouded making it useless. Would be easier to use if bubbles were larger, but this is a minor niggle given that a like-for-like replacement of the level would have cost c. £50.

I have a 3 ft aluminum spirit level with 3 bubbles, 2 of whish had clouded overMeasuring them matched to this item so I ordered the pack.No problems fitting them - almost an exact like for like. One was just a little snug when refittingEasy to read.As others have said the bubble could be little bigger, but its easy to read and the green fluid gives good contractGot a lifetime's supply now thoughThe low cost for these avoided throwing the spirit level away and the cost of buying another one so great value on that basis alone

I do not know how long they are going to last but for the time being they look good.

I saw complaints about these (and many similar products) not all being calibrated the same, but mine all seem perfectly level with each other. Problem is, I only needed one. Anyone want nine more? Maybe I'll stick some to the cat. You know... For science.

Bought as a replacement for faded units, would have preferred the bubble to be larger so that it reaches to the lines.

Restored my old 35" level to proper functional condition.

I used them to repair a damaged spirit level.
