Do you think it's necessary to purchase two?

YES! I purchased one because I already had one. I would burn myself if I didn't have two gloves on. This way you can go back and forth from side to side. I always have a limited time so I need to spend as much time on one side as the other. Hope this helps!

I consider myself fairly adept at these things and find it easier and faster having both hands covered.

Yes, you buy two so you can use as a pair for left $ right. They are NOT wireless.

To be honest I really don't think one is needed. However, if you place two batteries in tandem for more speed and power then I might put one on.

Yes you would need to purchase two, we put our one in a large corner and it gives our baby girl more playroom! :)

I only bought one. Three years later the other one is still good. Probably doing both makes the most sense.

You do not need to purchase two. If your system only has one sensor that's all you need. In my case, the water sensor failed and this item replaced it perfectly. My system's original air sensor is still working fine and I expect it will for a long time as it is sheltered from the elements.

There is only one per package so you would need to purchase two. But they are worth every penny!

I bought mine for the same purpose. Yes, you need two, and yes, one on each end.

Yes , you will need one per side! They are pricey but very nice. I love mine!

I only use one. That's my preference. Depends on what environment you plan to use it. I'd would purchase one. Determine if it meets your need thus, you may or may not want another.

No, you'd need one for each, unless they're networked together in some other way.

Yes. You won't need an extra one immediately, but if you ever do, they supply them separately.

The price is for each (ea) speaker. So, if you want two you need to buy two.

You should only need one until he/she gets big enough to need two for a bigger area. One should work fine at first.

Sorry Carol, I'm not a retailer just a person who also bought one. I still have two in good working order so I don't really need to buy another. Thanks for the offer though.

Yes, you'd have to order two. I got mine for $500 for the pair from Music123 I believe.

No. They work independently. However, if you own one, it is likely you will want the other after awhile because they work so great together.
