Water Level 10m x 3/8" is rated 2.6 out of 5 by 9.
Rated 3 out of 5 by from Works but tube had too many kinks +cheap quality Its best to invest more and get a tube that is fatter and stronger like a hose pipe. This one although works doesnt do it for me, plus when filling with water it took ages because the pipe is so skinny you naturally get air bubbles.

Rated 4 out of 5 by from Cheaper than a Laser Level! Simple but it works, this is a great little tool. The graduation measuring cylinder end pieces give an indication of level variation which is very handy. Only negative is that the tubing is greased in a few spots where it ha been coiled over tight to package it,

Rated 5 out of 5 by from Great product if you have sufficient intelligence I purchased this after reading the 1 star reviews.......... How to use; 1. Take plastic tubing from packaging and snip off the tube ends that have been bent over and tied. 2. Put the tube into a bucket of hot water to soften it and loosen the kinks. 3. Unroll the tube to remove twists 4. Push on the measuring vials onto the softened tube ends. You should just be able to reach the thicker part of the vial serrations. This eliminates water leaks. 5. Connect a garden hose to one of the vial tops. The ticker serration section suits a bare garden hose. 6. Turn the hose tap on holding both vials and slowly increase the water pressure so that you blast the air from the tube so that only water is in the tube. 7. Once the tube is full of water with no air present, turn off the hose tap and seal both vials using the push-on stoppers. 8. Position the vials ready for measuring. 9. Remove the push-on stoppers so the vial tops are open to atmosphere. 10. Measure and compare your levels. Temporarily lift/lower a vial to promote water movement in the tubing. If free to flow, the water in the vial with oscillate up and down as the inertia of the water flowing back and forth in the tube settles down. If you hold both vials together they should settle at the same level. If they don't, then you either: a. Have air in the thin tube b. Have the push-on stoppers, sealing the vials, still in place. They should be off. c. Have the water in the tube at different temperatures, for example, sunlight warming up one section of tubing. For the money, this is ideal but does require some patience and common sense to use successfully.

Rated 1 out of 5 by from Not fit for purpose Totally didn't work, the printed measurement markings on the tubes started in different places, so with the tubes side by side, and the water level, one tube read 2 on the scale, the other tube read 2.7 on the scale. Totally unuseable

Rated 2 out of 5 by from Does job Despite being guaranteed forever,the first time we used it it leaked around the joints between the clear plastic graduated tube and the hose connectors. Given the price and the one job we will do with it it does the job but anybody wanting more from it may be disappointed. Toolstations part was fine.

Rated 1 out of 5 by from Complete rubbish and waste of money. The pipe is so kinked in the factory the water doesn’t flow freely enough to level out at each end, which gives false reading (I’ve checked this with a spirit level). It the same as bending a hose pipe to stop the water flow. Also the holes at the end of the plastic ends are so small they also don’t allow the water to freely flow. Also unless you force off the plastic end of the filler it’s very near impossible to fill as no funnel will fit – I know I have lots of small ones for other jobs. It doesn’t work. Best bet go to a local timber merchant and get a long bit of wood which has parallel side (the timber merchants can plan it for you) then stick a normal spirit level on it.

Rated 1 out of 5 by from Poor quality The quality of this item is poor. The hose had several kinks when unpacked. I had to use a hair drier to try and remove them. I then assembled the sight glasses to the tube and filled it with water. It leaked at the joint between the graduated tube and the red hose connector on both graduated tubes. It could do with some hooks to hang the graduated tubes in the vertical position to avoid spillages/entraining air.
