Worked well for copper electrolysis, if you are planning to use it for this purpose use 200g-300g per liter of water with an appropriate electrolyte (sulfuric acid, white vinegar or salt)

good product

Excellent for killing roots in toilet pipes

I used this to kill some unwanted growth in a hedge to do this I drilled 13mm holes around them at 45 degrees as deep as you can and fill just when the leaves start to fall and again when the holes are dry and it works a treat

Can’t comment until next year then I can tell you if it has worked or not

As described

Just the job.**

Excellent product have used this before and is always satisfactory

Non mi è ancora arrivato niente, dopo più di 10 giorni. E meno male che la spedizione ho pagato come un pacco che dovrebbe arrivare in 1 giorno. Mi hanno consegnato una ruota per la macchina al posto del prodotto ordinato (ho rifiutato senza fare la foto – il mio errore). I soldi? Qualcuno ha guadagnato, ma non io. Ужасно! Никому не советую, эту же вещь можно купить у других и дешевле.
