I usually just look at the 3 star or lower reviews anyway, you're more likely to get an honest appraisal!
Mpow certainly have a few different names. These are the mpow h19s for example.. https://www.amazon.co.uk/dp/B095K8DJ6C/ref=cm_sw_r_cp_apa_glt_fabc_XT3V6XAARZSB530HMBMJ
What names can they be found as now? Looks like more brands have vanished since this thread was posted like RavPower and Choetech
Still there, just under different names now
I used to do lots of reviews but if the product was bad I either refused to leave one or returned it and left a bad one, knew lots of people who even if sent a completely broken item left 5 stars anyway though which ruins it. Pot, kettle, Black, this site literally has a team of people incentivised to post poor but sponsored deals XD
