Bosch Professional laser measure GLM 40 (with memory function, measuring range: 0.15–40 m, 2 x 1.5 V batteries, protective bag)

This is such a good item; it's absolutely tiny and comes with a neat little case. it's really simple to use and has some advanced features which I'm yet to use. So far have measured so many distances in my home with perfect results. Thoroughly recommend.

i use this almost every day! Small and compact. Great product when a tape measure just doesn't cut it! has never let me down with measurements. Worth every penny.

Great product, good features and easy to use.

20 meters is the max range on a white wall by day.

This is one of these things that once you've got it, you realise you should have got one a long time ago. I'd considered the Leica, but couldn't stomach the price, and I've always had a good experience with blue Bosch things. It has a variety of useful features, which I find I can't remember how to work when I get on site, so I basically use it as a tape measure. It seems fantastically accurate - I'm usually measuring between 3 and 10m, and it agrees with my Stanley tapes over these distances to the millimeter. Compared to using a tape, measuring an 8m wide wall to find the centre is crazy fast and an absolute doddle with this. The little red laser dot is highly visible, and shows exactly where your measuring, which is a great help. For anything over 3m, this is now my go to measuring device.Battery life seems great, it's absolutely tiny so you can stick it in a coat pocket, and it's supplied with a nice quality nylon belt holster if you prefer that.

Feels very well made, the rubber over-mould is great in case it gets dropped.The display is clear and it responds quickly.Indoors the laser dot is easy to see at 50m, but at 52m it refuses to measure (obviously it's only rated to, and limited to, 50m to make you buy a more expensive model).The triangulation feature using the inclinometer is impressive and accurate (my older laser didn't have that).If you buy the Bosch USB rechargeable battery pack for it (which I did) be aware that it only has about 1/3 the capacity of a couple of regular Duracell batteries (I checked the mAh ratings) because the rechargeable cells are smaller than AA in order to fit inside the secondary casing that fits into the space of 2xAA cells.After reading reviews of poor battery life I thought I'd use the rechargeable pack to save batteries, but I don't because it's annoying to recharge halfway through a job when regular batteries seem to last so much longer.I would have bought the longer range model, but it looks less robust (not rubberised corners) so I opted for this one. But I rarely need to measure >50m.

Brilliant piece of kit.

It's better than the red beam, the green dot is easier to see even in relatively bright sunlight, but it's not much use outdoors in full sun.The measurements are very accurate, although I usually subtract 0.5mm to ensure no interference when fitting things into recesses.Battery life on the green version is also better than the red laser
