A:AnswerIf you leave it outside the hot tub. It is not waterproof, just spash resistance. Even if you get a waterproof speaker, I would caution dumping it in the hot tub. Check that it can take the hot temperature. Heat is the enemy of lithium rechargeable batteries. It will shorten its life.
A:AnswerHi pat,
This speaker is compatible with echo however, using this as a remote speaker for your TV is not guaranteed to work perfectly.
Thanks,

A:AnswerIt works very well with my Echo Dot. And because it is totally portable it can be carried around my dwelling to any convenient place. Don't know the Blue Tooth range because my dwelling is small. Connection to the Dot was easy with the Amazon Alexa app.
A:AnswerI know the local Beat Buy where I'm stationed doesn't give no military discount but, instead, does like deals.
Example: Spend $50 and get like $5 back. I believe that's what it is but I don't really recall how much they give you back. I know it increases the more you spend so it's not too bad. Just ask your local Best Buy!
