Tronica Bluetooth Rechargeable Multimedia Portable Digital Display Speaker with Karaoke Mic MP3, FM, SD Card Support, USB and Aux Cable Support, All Smart Phone-A Unique Teaching Tool

I like it sound & features and wireless mic also.

Absolute junk. I put it for charging with the unit on (apparently you are supposed to turn off the unit while charging) and it never turned on. What a poor design and an utter waste). I never even used it once

It's a really a superb productsVery useful for Coching classes and small events and partiesHave good voice and eco soundHappy to have Tronica Mobile speaker with mic, blutooth and remote

It has a US power plug. So difficult to charge anywhere.As far as product is concerned after using about 11 months, occasionally use i can say it's not that bad product.May be suitable for small room.A class of 100 students may not offer u good performance. But it will definitely reduce ur stress in speaker louder.Means it will give ok ok performance for such large crowd.It has usb for playing it. Have tried it once to check. It's fine.FM works very well. In ur home u can use as fm and good sound.Charging stays for days.So much strong in battery.Using in class uses less battery power it consumption of battery is less. Effectively I used for about 10 lectures w/o charging.Helps a lot.And NO it doesn't have a Bluetooth.Mic wire is cheap. It's difficult to handle and I have to take care about it a lot..

It's a fantastic device at a low price. But then why 4 stars! It deserves 5*, but at my first order the machine breaks down within a couple of days, But replacement is not an issue. The replaced product is being used regularly up till date. No problems. Sound output, mic, is good at full vol.in a 20' x 10' room. I am a teacher. Remote is also goodFM reception little bit problematic.but no major issue.overall very good produdct. I*less for initial breaking down. I can buy one more.

This one is of poor quality like China product. Radio receiver poor and doesnt pickup signals. Belt clip got loosened on first use poor quality plastic. Waist band is with keychain rings instead of clips and very difficult to attach and use for teaching. Only positive thing about the system is: sound quality and microphone are good. Battery life four to five hours only.I am currently using PA system of Ahuja brand since last five years and it's bit costlier but very nice, convenient and have longer battery life.

Good productBattery backup is excellent

Remote does not work, pen drive did not work, bass is not available, I got to return it. MP3 from local market will do better. Total useless. Don’t know why others wrote good reviews!
