Use lamp lubricant

This is amazing! Value? I laugh at the one star reviews that broke the glass tip trying to force it to dry the bulb. ๐Ÿ™ˆ Maybe you've never had a chemistry class where the teacher showed how to smear the glass with glycerine before putting it in the lightbulb. This is useful advice - it is useful in many areas of life - everyone should learn it

Pros
  • This is amazing
Cons
  • Some bugs

Good pipettes for brewing and hydroponics

I bought these to use for acid addition in brewing and hydroponics for pH adjustment. The things were well packed, nothing was broken upon arrival. The kit contains two glass pipettes with rubber bulbs, two glass stirring rods and a cleaning brush. The only thing I don't like is that they aren't quite like the pictures, where there is a number for each full measurement in milliliters. While the ones I have received have a wide line to represent each full ml, the glass droppers only show evenโ€ฆ

Pros
  • Weight
Cons
  • Some little things

Higher quality than the local store and better value for money!

So I buy most of the things I buy on Amazon because of the money I save. This product is no different. The price comparison was relative, but the additional features appealed to me. that it came with 2 glass stirrers. Which I needed for a cylinder set I bought and didn't want to buy a new agitator pack. So it was absolutely perfect. The glass quality was at least 0.2mm thicker than my local shop. But at a price where I get 6 for the cost of 2. I found it to be excellent quality with exceptional
