Kargo ambalajı çok zayıf kendi poşeti ile kargo poşetine konulmuş geldi,
daha korunaklı paket ve ambalajlı gelmesi gerekirdi.
Şansıma, ekranında herhangi bir kırılma ve deforme olmadan elime ulaştı.
Çoktan beri almak istediğim üründü, uygun fiyatlı gelince Banggood'dan alma şansım oldu.
Ürün aynı özelliklerinde anlatıldığı gibi güzel çalışıyor, benim için Amatör elektronikçilere müthiş bir yardımcı olacak.
Banggood'a ara sıra sunduğu indirimli ürünler ve hızlı gönderim için teşekkür ederim.
The cargo packaging came put in the cargo bag with its own bag very weak,
It should have come in a more secure package and packaging.
Luckily, it reached my hand without any breakage and deformation on the screen.
It was the product I wanted to buy for so long, I had the chance to buy it from Banggood when it came to affordable prices.
The product works well as described in the same specifications, for me it will be a great help for amateur electronics.
Thank you to Banggood for the occasional discounted items and fast shipping.

Q:
Where can you buy a case for the transistor tester?
Where can you buy a case for the transistor tester?
I got this one from Amazon: "SHOTAY Transistor housing, transparent acrylic housing shell box for the capacity of the LCR-T4 ESR transistor tester". The case had a small misalignment of hole in a side plate so I just sanded out 1mm x 1mm of a side area to make it a perfect fit. I am quite satisfied.
