The product performed as expected and was delivered within 2 days of being ordered! I had a problem with the previous Amazon supplier of this product. Amazon promptly refunded my money and followed up with this supplier to make sure I got what I ordered within 2 days.Price drop in 3 weeks was considerable. Hopefully they will give me back the priceDifference. Was not the first purchase with this company. Isa good product and they ship fast. Need to watch the pricing. $439 to $399 was big plus savings on tax.This product did save me a bit over my local pool supply store.The price of Bromine has really gone up. We used to get 100lbs for less than the cost of 50lbs now. Of course everything has gone up. It is exactly what we use and it's nice that it doesn't come in little plastic bags, first time in a long time, quicker to use. The only thing was that we had to sign for the delivery and we never had to from the prior supplier we bought it from. Someone was finally home on the 3rd delivery! Not sure what would have happened if we were never there when they delivered.Not chipped or broken like I so often get. Only wish the bucket was a screw top lid as shown in the picture. The one I received is a snap top that is sometomes difficult to remove and replace.Easy open and works as it should. The tabs last the appropriate time, usually around a week and a half or so.These bromine tabs are correctly in the bucket. Other brands I've used are randomly poured in the bucket. That resulted in excess powder created during shipping. This leads to bromine powder that doesn't work like the tabs. Bottom line is more useable tabs and less waste.A good value for the hot tub.
