### ⭐⭐⭐⭐⭐ Bad experience for my birthday.
*by B***0 on May 26, 2022*

I bought this speaker cause i heard good thing about it , i get the Boom 3 , my friend told me to get the megaboom, but i get the small one , i was so excited ,i get it one day before my birthday and next day we was going to the beach to celebrate, i put the speaker to charge but i didn't check if really was charging (new product) why to check?.. well next day 2 hours later when the party begins , the speaker died 😢😢 i was really upset all day on my birthday , i had a portable charger and wasn't working, came home put it to charge and nothing , i try other cable , other plug and nothing... I contact Amazon customer service and they replaced for a new one... Today 05/26 put the new speaker to charge and is charging so far , sound beautiful ❤️ but is too early to give them 5 Star ⭐⭐ i will change the start when i am confident that is a really good product ... Updat.. today 03/21/2024 almost two year I get this speaker... I will give them 5 stars cause this radio speaker still perfect, still sound nice and battery life is great.. I bought other one cause u can connect other speaker through the Boom app in the same channel and play music together. 💓💓 It said is waterproof.. well yes it is .. I am really bad and put the speaker inside of my pool 🫣 ofcourse will sound horrible but I took it out and the speaker still good and sounding beautiful 💓💓💓
