When you secure the rod with a nut in the base, I found the whole thing a bit wobbly. Tightening the nut firmly is possible, but it causes a plastic ring at the top of the base to give way. If you replace that plastic ring with a steel ring, you can tighten the nut firmly, which makes the stand a lot more stable. Furthermore, the included clamps and connectors are good to use.

A little late and some problems with the delivery, but it arrived well, nothing broken or damaged. Surprisingly a lot of ph paper included and everything is there. For this price, a very comprehensive set that you won't find anywhere for that price. The quality looks good. So I am very happy with this set.

It takes some time to figure out how to assemble it, but with a little help from a friend we made it work! It’s a very high quality set with the exception of the alcohol lamp, which is simply not strong enough. I recommend buying a little electrical stove to heat things up, as it took us a few hours to realize it wasn’t going to work haha
