Customers say
Customers find the weed killer works better than other products, is easy to apply with the pipette, and appreciate its strength. The product receives mixed feedback regarding weed growth – while some report no regrowth, others mention very little regrowth. Moreover, color changes are noted, with leaves turning brown, and opinions on value for money are divided between those who find it worth the cost and those who consider it overpriced. The weed control aspect also receives mixed reviews, with one customer noting its effectiveness against Japanese knotweed.
