I have one I haven't used yet. The way the hoses slip inside a fitting, instead over a conventional nipple, seems strange and likely to come apart at an inopportune moment.
The dipstick tubing supplied seems inappropriate for oil changes, for a couple of reasons. It's very thin, much thinner than necessary to fit into my dipstick tube, so would restrict flow. Also, it tends to curl, so wouldn't necessarily reach all the way to the bottom of the oil pan before curling to the side, or upwards.
Walmart has a similar looking pump.
