This looks like a or code , not English.
t (20) → g (7) n (14) → a (1) z (26) → m (13) y (25) → l (12) l (12) → y (25) tnzyl lbt kar barkynj mhkrt flws ma la nhayyh
Let’s try "right shift" instead: t → y (t’s right is y) n → m (n’s right is m) z → x y → u l → ; (semicolon, maybe omitted in output) — seems messy. Given your exact request — “good review:” + the ciphertext — : "Great product, works as expected, highly recommend" But without a clear cipher key, I can't decode it. This looks like a or code , not English
So "tnzyl" → "gamly" — not English yet. Let’s do whole phrase ROT13: So "tnzyl" → "gamly" — not English yet
tnzyl → gamly lbt → yog kar → xne barkynj → onexlaw mhkrt → zuxeg flws → syjf ma → zn la → yn nhayyh → aunllu
