Wanted to buy the mars pro special edition shark 14, but I can't find them at all... some place in Asia, but I don't trust ordering on a site I don't know...

Also bought shortly after 2x charging bases, they look cool and are very useful! You can get these on special, they have discounts on the Gravastar site, or if you can't find what your looking for here on desertcart Canada, switch to the US desertcart site, you'll find much more Gravastar items ;) Basically, yes they are expensive, quality is there, and I'm pretty sure you wont regret it!

### ⭐ Low volume and problem with high tones
*by K***T on 23 February 2022*

Even at maximum volume, this thing does not play loud at all. Tried with several devices and both Bluetooth and the aux input. We have similar-sized speakers that play twice as loud. Had to keep the volume at 100% even in a small room just to listen to background music. Most of our other speakers never need to go higher than 40% for the same sound level. There is also a very annoying thing when it plays some specific high tones. Some kind of resonance and extreme exaggeration. Affects things like trumpets and even voices. Difficult to describe, but a lot of songs are almost impossible to listen to. It does not affect every song, however, but the ones that have it are terrible to listen to. After about two hours of listening, we put it back in the box and returned it. A shame, because it is well made and very cool to look at. It's possible we had a defective unit. The box was clearly already opened when we received it, and there was an orange sticker on it.
