Abe, I've had mine on since last Christmas and not used the other two, and it seems to be in great condition. I do have a Bobj rugged case that wraps around the front so the edges aren't exposed. I also used this method to install the film http://lifehacker.com/5927704/apply-a-screen-protector-perfectly-every-time-with-the-hinge-method

I don't think so, I suspect it's just back up..I didn't realize it was a 3 pack until I opened the pack

That's for one. If your buying cools for under $20 each, you should plan to change them frequently. Once a year or so

Save them to when you need them. After a while they tend to get a bit scratched so you can change them.

When I am not sure of the amount I will get if its a good deal I will order them. Because of the average cost is usually 2 for $5 in a store. So it would still be a better deal then in a store. Also most of the time there is usually only 2 per pack. I don't know if there is one that comes with a three pack but there maybe. If it was me I most likely would order it if you give them at least twice a week.

Hello, we sell them on Amazon in both 3-pack and 6-pack quantities. The 3-packs are $9.60 and the 6-packs are $17.90. Hope that this helps you.

Just doing some simple math here. One of these lasts for about 3 months in use (1/4 of a year). This means that you would use about 4 in a year (Less if you experience winter). They sell these in 6 packs, and they are only good for a year unopened. Doesn't this mean you're throwing 2 or more of these away every year? Scratching my head over here.

I use one about every 2 weeks. If you keep them clean they last a long time

It comes in a package of three. And they can be a little difficult to put on if it is your first time. But they are single use. I can't see using them more than once.

you are suppose to change them out every 330 days If you don't change them. the water flow will go to nothing. because of the cost I would never put one in my house

Hi John, if you keep them plugged in continually (which is what I would recommend for full effectiveness) then each bottle lasts about a month. I actually have a reminder in my calendar to change them out. I forgot once at the end of a month and paid the price a week later. :)

each month has a different combination.that's why they want you to change each month. So other than just a different combination. My husband would use 1 month for up to 2 months sometimes and then switch.

unless its changed since I bought mine in the late spring; you get one. They are worth it though.

what color are you looking? if it's the green one it's not included here and it's a bit pricey compare to these 3. You only need to change the green once in every 5 years.

3 pack is being sold by Amazon and 2 pack by a third party seller. That's probably the reason for the price difference

Get on Holmes mailing list they have sales on regular basis. There are no 3 packs that I have found though
