有点 is typically used before adjectives with a slightly negative or undesirable nuance: 有点贵 (a bit expensive), 有点难 (a bit hard). For positive qualities, use 一点 after the adjective instead: 好一点 (a bit better).
mistakes
Don't confuse 有点 (before adjective, slightly negative) with 一点 (after adjective, neutral/positive). 有点好 sounds unnatural; say 好一点 instead.
