no communication/help
1.) I thought the Calculator was an excellent tool; but, when I needed to re-measure my trap door details, and entered new numbers, they didn't actually replace the original measurements I'd entered--even after exiting the gasspringsshop website and closing the browser. So, when I received confirmation of the order, one of the measurements "B-Green" on the order confirmation diagram was incorrect . (Isn't there a way to clear data to start over?)
2.) The order-processing speed was impressive; but was so fast I couldn't make the change to "B-Green".
3.) When the package arrived, there were no instructions in the box. The #'s on the gas springs: 0240N WS23106US 33/22
did not match any numbers on the order: 8-19-300. I called to get clarification; but no one answered, and no one responded to the voice message I left.
4.) I installed the gas springs, and they are an improvement on the previous auto-parts store gas springs, but the trap door is still quite heavy to lift from horizontal floor level and is heavy to control closing the door back to floor level.
Perhaps I'd have ordered a different pair if I'd actually gotten some help.
