The Trolli Halloween Sweet & Sour Bag is highly popular with children and frequently purchased for Halloween events and trick-or-treaters. Many adults also found the lollies delicious, appreciating their sweet and sour flavour profile. The individually wrapped nature of the lollies is valued for hygiene and portion control, particularly for distribution. Customers often consider them good value and express an intent to repurchase, with the fun, spooky, or Halloween-themed shapes and packaging being a positive attribute. As a seasonal product, some consumers stock up on them. While generally enjoyed, some reviewers found them too sugary or tart for their personal preference, or noted the presence of sugar and artificial colours. The texture was occasionally described as chewy or gelatinous. The product often receives positive remarks regarding the consistent quality and creativity of the Trolli brand.
