Grass Lawnmower Trimmer Strimmer Plastic Blades Compatible with Gtech ST04, ST05 20 Pack

A bit tight to fit and a little more brittle. But they do the job. Good value compared to original.

Easy to use

Arrived promptly. They are fine for cutting through vegetation but are quite brittle and break easily if you touch a hard object. I went through a third of the pack doing the edges of my lawn. Pliers are needed to fit them on to the strimmer head.

Break quite easily so went through a few each time

Original gtech blades wear down over time during use (see green blade from photo) but these replacements shatter very fast (multiple black blades). Lost more than shown in the picture in a single garden strim as some completely smashed and bits flew away.To put into context, I used 17 out of the pack in 1.5 hours of strimming where I would usually use 3.I assume the plastic used is too brittle/hard and don’t wear like original blades that are more flexible.Shame as they were decent price and delivered promptly

Poor hard plastic difficult to make fit

Great replacement blades

THEY DO THE JOB
