I just got a little use out of them so far, but I like them. I bought the APC in 32oz to try. You can adjust the sprayer more to you liking compared to the 16oz bottles and the bottle is in the price of the product so you are saving the 6.99 compared to buying the empty bottle and product. I will be buying more products in the 32oz size for the bottle, sprayer, and because I use more than a 16oz bottle, but not a gallon fast enough in most products. I already have a stock of supplies, but the new 32oz bundle is nice.
