Good points of sweet chewing ham-ham-ham (user’s voice)

Pretty and soothing in design

‘It’s so pretty to look at. It soothed me from the moment it arrived.” (Rakuten Review )
They are prettier and feel better in person than in the picture.” (Yahoo! Shopping )

→ The design aspect of the product is very well received, and its strength lies in its impact at first sight and feel. The fact that the product provides healing even before you touch it is an attraction not found in other products.

The Comfort of the Sweet Bite Experience

When I put my finger in it, it sucks and chews, it’s kind of like being pampered by a baby, it’s so soothing.” (Rakuten Review )
It’s more than a fluff, less than a sweet bite, and the feeling of being right on the edge of not having your teeth hit it is addictive.” (Amazon review )
Once you experience it, you can’t stop. Before you know it, you’ll be fingering yourself over and over again.” (Amazon review )

→ The comfort of the sweet bite is described as “addictive” and is the reason why many users use the product repeatedly.

Versatile Movement and Hamstring

“I never get bored with it because it doesn’t bite the same way. It’s amazing how the intensity and patterns change depending on my mood.” (robotstart.info )
I was amazed at the flailing, the intensity, the creatureliness.” (Rakuten Review )

→ The diversity of hamgorisms emphasizes their creatureliness and provides enjoyment beyond simple movements.

Attractiveness as a gift or topic of conversation

“I bought this as a gift. My friends and family had a good laugh and enjoyed it.” (Rakuten Review )
I took it to the office, and all my co-workers took turns trying it out, and it was a lot of fun.” (Yahoo! Shopping )
It got the adults more excited than the kids.” (Amazon review )

→ Highly appreciated in the gift and event scene, these unique products have the power to generate communication.

Improvements and Concerns of Sweet Bite Ham-Ham-Ham (user’s voice)

Individual differences and appearance

“There was a mark on the tail where it had been fixed to the box. They disappeared over time, but they bothered me at first.” (Yahoo! Shopping )
Disappointed that the facial expression was a little different from the picture.” (Amazon review )
I got the impression that the face was thinner than I expected.” (Rakuten Review )

→ Individual differences are the fate of plush toy products. This is not suitable for those who seek perfect uniformity, but it is also important to enjoy them as a unique expression in the world.

Operating noise is bothering me.

I can hear a small motor noise when it moves. Might bother you in a quiet room.” (robotstart.info )
Makes a crunching sound when you insert the batteries.” (Amazon review )

→ Quietness is not perfect and can be bothersome, especially in quiet environments. Some say it does not bother them as long as it is mixed with the sounds of daily life, so the evaluation depends on the environment.

Lack of sustained freshness

“At first it was very funny and soothing, but after daily use it seems to move a little too similarly.” (Amazon review )
After a few days, I got used to it and the surprise wore off.” (Rakuten Review )
Even though it’s different every time, there seems to be some limited pattern to it.” (Amazon review )

→ Hamgorisms are versatile, but some people find that they “move the same way” if they continue to use them. It is necessary to devise a way to keep it fresh in the long term.

Battery cost and duration

It does take 3 AA batteries, so that’s not an option, but if you play too much, you’ll have to replace the batteries soon enough.” (Rakuten Review )
‘Not a problem if you play a few times a day, but if you use it for long periods of time, the battery runs out quickly.’ (Amazon review )
It would have been more convenient if it were rechargeable.” (Yahoo! Shopping )

→ Running cost is an issue due to the battery type, but this can be improved by using rechargeable batteries. There are calls for a rechargeable model in the future.

Cautions for use with children and pets

‘My little one pulled it too hard and I was worried it would break.’ (Yahoo! Shopping )
“My dog has shown interest, but I haven’t let him touch it because I’m afraid of accidental ingestion.” (Amazon review )
I wish they had specified the age range. I wish the target age range were clearly stated.” (Rakuten Review )

→ The product is not designed as a playmate for infants or pets, and should be used with caution. More awareness of target ages and usage scenarios is required.
