Example Input: I absolutely like it The brain booster influences well on my alertness and memory. I feel much more clear after half an hour of taking them. I think that they even improve my critical thinking.
Example Output: positive

Example Input: I got the 6 foot tree and fit perfect for an apartment. Be away 6 foot means including the stand and the long top piece that the angel or star sits on. It fluffed out well but will need to vacuum before and after assembly.
Example Output: positive

Example Input: I initially received the product in used condition and was pretty disappointed and upset. I am revising the review now as the seller was very genuine and tried hard to provide solutions and explained the situation. Overall we were happy with how it turned out, and it's a nice scooter and my son loves it. The seller was very easy to work with and I think he/she sincerely care about the products/customers.
Example Output:
positive
