Query: Great OEM type product

Great product, fits like a glove. I simply matched up the trimmer head I have and the ones listed and it fits great. If you have a model listed and you buy a replacement head from Home Depot, it will likely not fit as the common ones they sell there are for newer models, and not the older styles like this is. I bought 5 so that I can fill up all of them in the beginning of the day and not have to waste time with refilling the line. Great time saver! It's made by Stens, which makes great replacement products.
