It's very good!! Hangul Manual!!! until C type charge... just exercise! ^ ^

The delivery took exactly 5 days due to domestic holidays, and the product is easy to use for beginners it's in Chinese, so it's less of a burden than Chinese.

I bought it cheap and it arrived really fast. The products I received are in count, time and English.

The first time I had a problem with the product, but it was done well with the seller's quick response. Yes.

I bought it out of curiosity just because it's a count, and it's very good.
From the basic count to the 100 station count.
It's a timer, and it's more functional than you think.
There are Springs, so strength is good for beginners or intermediaries.
It's a little easy for advanced self.
The product is great because it is big and heavy.
It is recommended when the ab rollout with no function is boring.
