REVIEWS


UA Works Really Good. For Now Tested Only With Led Light (that's The Only I Have Had In Hands) On Lowest Frequency, But Duty Cycle Tested Completely (it Works!). If I Don't Forget I Will Leave Additional Feedback After Real Testing. Recommended! 05 Sep 2020 13:47

RU Delivery About A Month With Other Goods. Packed In An Antistatic Bag, It Would Be Possible And Better, Because. LCD Is Easy To Damage On Delivery. Turns On, Works. The Build Quality Is Normal, Only Flux Is Washed Badly. When Setting The Frequency More Than 100kHz Constantly Burns The Point Of Lower Frequency Discharges, So Should Not Be. In General, Good. A Useful Device. 26 Sep 2020 03:46

UA Instead, The Generator Came With Some Kind Of USB Crap Clearly Cheaper Much. Then The Letter Came After The Complaint That I Would Close The Dispute With The Offer Not To Return Anything To Me. I Sent Pictures Of What Came. Made A Request For A Refund Of All Amount Including Shipping. Ali Returned Everything To Me. Therefore, For The Loss Of Time Minus The Star, For Additional It Is Free USB Crap Additional To The Star. 05 Nov 2020 17:04

RU Описание соответствует. Доставка неспешная, трек отслеживался только до "импорт в страну назначения". Качество сборки очень хорошее. В работе пока не проверял. 31 Jul 2020 23:45
