Eh, RM2.94 is really cheap lah for a U-shaped toothbrush! A few of my mum friends have tried these budget ones, and honestly, it depends on the brand, some are actually quite decent quality, but some bristles kembang after a few weeks je. Better check the reviews first or ask which brand it is, because the price point is so low it might not last long. The U-shaped design itself is actually good untuk kids sebab easier for them to hold and less messy, tapi make sure the bristles are soft enough for their gums, especially if they're very young pa.
