It's soft and \ super cute, and its face has a friendly look. It's \ a bit small for what I paid though. I think there \ might be other options that are bigger for the \ same price. It arrived a day earlier than expected, \ so I got to play with it myself before I gave it \ to her. ``` #### Summarize with a word/sentence/character limit 30个单词、一个句子、没有角色限制 ``` Your task is to generate a short summary of a product review from an ecommerce site.

""" # review for an electric toothbrush review_3 = """ My dental hygienist recommended an electric toothbrush, \ which is why I got this. The battery life seems to be \ pretty impressive so far. After initial charging and \ leaving the charger plugged in for the first week to \ condition the battery, I've unplugged the charger and \ been using it for twice daily brushing for the last \ 3 weeks all on the same charge. But the toothbrush head \ is too small. I’ve seen baby toothbrushes bigger than \ this one. I wish the head was bigger with different \ length bristles to get between teeth better because \ this one doesn’t. Overall if you can get this one \ around the $50 mark, it's a good deal. The manufactuer's \ replacements heads are pretty expensive, but you can \ get generic ones that're more reasonably priced. This \ toothbrush makes me feel like I've been to the dentist \ every day. My teeth feel sparkly clean! """ # review for a blender review_4 = """ So, they still had the 17 piece system on seasonal \ sale for around $49 in the month of November, about \ half off, but for some reason (call it price gouging) \ around the second week of December the prices all went \ up to about anywhere from between $70-$89 for the same \ system. And the 11 piece system went up around $10 or \ so in price also from the earlier sale price of $29. \ So it looks okay, but if you look at the base, the part \ where the blade locks into place doesn’t look as good \ as in previous editions from a few years ago, but I \ plan to be very gentle with it (example, I crush \ very hard items like beans, ice, rice, etc. in the \ blender first then pulverize them in the serving size \ I want in the blender then switch to the whipping \ blade for a finer flour, and use the cross cutting blade \ first when making smoothies, then use the flat blade \ if I need them finer/less pulpy). Special tip when making \ smoothies, finely cut and freeze the fruits and \ vegetables (if using spinach-lightly stew soften the \ spinach then freeze until ready for use-and if making \ sorbet, use a small to medium sized food processor) \ that you plan to use that way you can avoid adding so \ much ice if at all-when making your smoothie. \ After about a year, the motor was making a funny noise. \ I called customer service but the warranty expired \ already, so I had to buy another one. FYI: The overall \ quality has gone done in these types of products, so \ they are kind of counting on brand recognition and \ consumer loyalty to maintain sales. Got it in about \ two days.
