عدم سرعة استجابة التاجر وعدم توافق الجهد الكهربائي في كثير من الدول.

لا انصح في شراء هذا المنتج لعدم توافق الجهد الكهربائي في بعض الدول ولايوجد توضيح كامل بخصوص الجهد الكهربائي. و صعوبة التواصل مع التاجر لارجاع المنتج منذ شهرين. ولا يوجد أي تواصل واهتمام. لا انصح بة.

Great pump for a great price

Bought this vacuum pump for performing lab tests at work and it definitely does the trick! Great price and it does exactly what I need it to do. Always check to see what CFM you require before purchasing so you don't order something under powered. 5 stars!!!

Great diy pump at a great price

Great diy vacuum pump. After making an AC line repair I drew down a vacuum for 45 minutes then shut off and watered the gauge for 30 minute. Not drop in vacuum indicated a successful repair. Saved $1000's doing myself. Would buy again
