Liquid Harvest Lazer Blue Concentrated Spray Pattern Indicator 8 Ounces Perfect Weed Dye, Herbicide Fertilizer Marking Turf Mark and Marker

As another customer said, the 8 oz. bottle that I received does not look like the bottle in the photo. The bottle that I received looks like a smaller version of the 16 and 32 oz. bottle. There is no provision for easily measuring out 1 oz portions inside the bottle. Instead of squeezing the bottle to measure and dispense the dye (like you would do with the bottle pictured on Amazon), I had to measure it the old fashioned way (pour the dye out of the bottle and into a tiny measuring cup). This was messy and far more inconvenient. So, be aware that the bottle you receive might not be the style of bottle pictured here on Amazon. IF spilled, the dye gets spread everywhere very quickly and it smears around when you wipe it up. Update: I received a response to this review from the seller offering a full refund due to the mixup about the bottles. 10 STAR CUSTOMER SERVICE! As much as I would have liked the bottle with the built-in dispensing feature, the product itself is great and performs wonderfully. And you can't beat the way the company takes care of its customers.

I get what i wanted

Très pratique pour savoir ou l'on utilise les produits de traitements. La couleur disparait en trois jours sauf sur les murs. ATTENTION Il faudra utiliser un nettoyeur haute pression pour faire disparaitre les taches. Utiliser des gants car sur les doigts ça reste malgré un nettoyage intensif.

I've usually just guessed how much liquid chemical I've applied before but this helped me make sure I got the right coverage. I barely used any in a 15l tank and could see exactly where I'd applied weedkiller. It made the job much easier. I did get some on my shoes but it wore off fairly easily with general wear,

Anyone who has ever sprayed liquid herbicide (or any chemical) over a large area of ground will appreciate the problem. It is tough to remember exactly where you sprayed and didn't spray. You end up with either large gaps, or areas sprayed multiple times, or both. This product helps out quite a bit. === The Good Stuff === * Once you get the hang of seeing it, the blue is distinguishable even on green grass. It helps a lot if there are patches of bare ground, or some dandelions or other flowering weeds, but you can see the blue even on grass. It helped me a lot wear polarizing sunglasses. * I mixed it per the label instructions. I suppose a little extra would have helped things along- maybe next time. * Cleanup wasn't as bad as I feared. The instructions mention bleach, but I just ran a little extra plain water through my backpack sprayer, and the blue dye cleaned up. There might be just a slight blue tint to the clear tubing lines on the sprayer, but it gives the thing a little class. === The Not So Good Stuff === * This stuff should really ship with a box of surgical gloves. The instructions say the dye will wash off skin with repeated washings, but I suspect it really means that once the skin wears away, the dye goes with it. And if you get it under your fingernails....well, good luck. * I was not a fan of the bottle. It didn't pour real cleanly, meaning the stuff dribbles down the side of the bottle. Makes for a real mess. A squeeze bottle, or some sort of pump would have been appreciated, even if it added a few cents to the cost. === Summary === In the end, the product did what it claimed. There are a few things that could have been better, but it solved a problem, and probably paid for itself in less double spraying. I would have much preferred a brighter color (yellow or orange), but I suspect the blue dye was the easiest to make work. If you are colorblind to blues and greens, don't even bother.
