Do you have to use all three componets?

No. You can use 1,2 or all 3. I always place the eye on the inside of my cabinet door in the vicinity of the component on the same level.

The kit will work for all three. It will come with three sets of instrinstructions and you will need to pick which design you want build.

You should be able to use all four together, but we had some trouble doing that the first time we used them. Honestly, we haven't tried since, because we purchased them for use in the warm weather. Sorry I can't be more help.

I does contain the top part. I don't know if you are supposed to use two if them but I did in my toolbox.

Sorry -- I don't either. Check the users manual -- I think most parts are not available individually.

You can use both, but I recommend you: don't but this product, is horrible. It has problem every time.

No you only need to use one of them . They just give you three if you need them. The screen saver stays on for a long time , I have had mine on since July without any problem.

Nope, you have to but those separately. You can fin them on amazon for cheap though.

Yes, all three at once. I feel you will be very happy with the purchase, I am very pleased with mine.

No. Everything was included. You could upgrade to a hardware kit if needed or desired based on your setup, but it's not necessary to start I'd say.

Hi Brenda. I've bought this product and you don't need to buy any other piece. You can use them with the content the box comes with.

Yes, everything required for installation is in the purchase. If it is a kit.Your need to bring up the number you are ordering, if a kit it will show all the components.

I used all 4 on mine. Don't think it's required but it steadies it up better

They come in separate pieces, so if you're assembling it for the first time, then yes; you can use only 2 if you wish. But if you've already attached all 3 together, they'll be pretty much impossible to separate without breaking.

You really don't need any. I got an extra set of everything because I get busy and don't always have time to wash and sterilize the parts every night after work, and it has worked out well.
