I'm looking for a couple of decent trigger-operated spray bottles for weedkiller - a B&Q bottle that I've used for a few years developed a small split just after I'd filled it. I've always used either domestic bottles for less harmful stuff (cleansers etc.) and emptied bottles of the same genre for 'nasty' garden stuff and so on.
Are there decent, robust versions that might not drip from around the mechanism, as most seem to do, and about a litre? Looking for ideas based on use, please.
