Have considered myself fairly capable with all sorts of DIY and can assemble flat-pack furniture with little more than a couple of glances at the picture usually....but nothing had prepared me for the Chinese and seemingly hieroglyphic "instructions" that came with this - was a table of random numbers but zero description of how to actually fit them..This is part of the reason they stayed on the kitchen counter for a few weeks, while I tried to get my head around how to do the fitting..With a combination of calculations and (multiple) tests to work out how they go, finally got to a position that meant they were able to both fully extend and also allow the flap to close properly......but....well........check the video..Am now unable to either have the flap [held by these] in the fully open *or* fully closed position....just a constant ⅓ open, meaning that it sticks out and blocks the light and gets in the way - am constantly half-expecting to knock my head on the corner of it.....Will be taking it off once this is posted....shame it's been too long to return them...

these work well and seem pretty sturdy and well made, however for my installation they didnt work first time as I wanted a wider open position than these would allow, so had to reduce the max open position so that they would collapse enough to allow full shutting again.Installtion instructions also useless unless you speak Chinese.

Very strong, does the job. Received an email with fitting instructions in English as only Chinese included in the package. It’s tricky but important to get it fitted in precisely the right place and the measurements/diagrams were helpful in doing this.

All good so far. No problem to install. Instructions in Chinese but the diagram is easy to read. Hope they last the test of time.

Did the job on my plastic garden box, I had to screw wooden blocks for them to screw into and all is working well.
