    • Good Value. But be aware it does NOT come with Mic adapter.
Why did you pick this product vs others?: To be honest, I thought I was buying a different product. I picked it because the item description said it came with a guitar/mic adapter, but it does not. =-( Value for money: Other than that, it does work well. It is a smaller size than I was looking for, but it does have good sound for the price. I have not tried it outside yet, so I don't know how long the battery will last. I have had other Monster speakers before and I liked the products. ... show more

    • Worth it!
Love this speaker. It’s light and small. Has good sound quality and the battery lasted us 4 days of camping. Mostly had it on in the mornings evenings. Took it on the kayak. It can take a splash. Good price. Will be getting another one😊

    • Warning: Do not buy
Listing stated the speaker is loud and has a 24 hour battery life. This speaker has very low volume, even with volume all the way up. The battery went dead after 8 hrs. And the speaker will only charge to 75%. On top of that, I can’t get it returned because the only return option is to have UPS bring the return shipping label, instead of just letting me print one out.sn adult has to be present whenever UPS arrives. I’m not home during the day. So, how can I return it?! Worse transaction and return I’ve encountered on Amazon. ... show more

    • Great value, don't leave in the sun
Great radio, with great sound. I have used this poolside and fireside for hours of music. The multi-directional speakers provide great coverage all around and this speaker BUMPS. I will note however that it is not something you can leave in direct sunlight. The paneling around the speaker controls has started to separate from the top of the speaker. Does this affect the ability to change settings/volume? No. Is it a nuisance considering I just started using the speaker? Yup. There does appear to be screws holding the paneling on, so it wont fall off completely, but the plastic panel has now warped. ... show more
