Stage of relationship with the supplier at the time of the incident:
I bought 3 power savers form Shenzhen Jumbo Power Technology, When I received the products, they came with wrong old user manual, I installed power saver and test 2 units for true test.
I test to 2 places hotels 1 room 2 air condition 2 hour without power saver , and 2 hours with jumbo power saver C100, and 2 hours with another power saving true.
after many test same time , same place , same conditions
1 detect the monitor screen show LCD show not true Power factor, show not true % saving. with a meter control test i see the evidence without power saver 4.1 kw/h for 2 hours. after test 2 hours same rooms 2 air (same conditions) with jumbo C100 power saver result: 5.1 Kw/h. i contact the factory and ask me i need hotel minimum load 45A , night time i test again i open many room for 60A for can try true,
I tested 1 hour without power saver.
I tested 1 hour with jumbo C100 = lost 0.04kw/h not win
I tested another power saver from another supplier same place same condition – I win 16%!
I showed picture evidence to the factory Shenzhen Jumbo Power Technology for getting a refund on the product, but they closed every communication. From the first test I have 1 friend in china seller others product I sent him every test in real time. he then also contacted Jumbo many times about the wrong user manual, and he participated in the dialogue with me and the factory Shenzhen Jumbo Power Technology. Yesterday he called the factory again, but nobody answers his calls anymore.
He contacted me and look for Monday go visit is scam factory not honest, also him approval he carries this witness for complaint to Alibaba. because during every test i send him every report every problem and him contact is factory jumbo every time.
Now the complaint with Alibaba a really opening and Henry Chen me friend china make everything for jumbo company come back full money. thank you very much china find good friend agent help for resolve problem, i report jumbo for scam, for product not true to is website because I make a true test and product not save!
Please note; Shenzhen Jumbo Power Technology company are gold supplier 4 years with a not true certificate third-party verification service provider by Hangzhou Zhongde Information and Technology Services Co. Ltd. website does not exist :www.hzzd-inc.com/en/index.asp
Also I blame Alibaba.com when you report a scam, they never close the account of the scam company, but only place a warning 90 days have 1 dispute. This is not enough to protect other victims.
I recommended is website can contact Henry Chen good friend agent him sale others product and can help for when have dispute with not honest supplier. him resolved last month 1 problem with another supplier. Actually the complaint just start have to wait about 5 to 10 days for i up can resolve.
I recommended is agent honest:
