“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work”
