Update....I have since received another SumUp 3g reader, a few days after typing that review up there, (my THIRD 3g reader) this has also been sent back for a full refund now. I've given up on that one. It is just too flakey to use. "Connection error" is too common. I'm sticking with iZettle now. I don't care about the tiny % extra. It's worth it.
Thanks for this response. really helpful!
Don't bother with the Paypal one it's very very slow to take contactless. I mean like 30 seconds slow. I have used the iZettle machine [since the original incarnation and then upgrade], and also the SumUp [Bluetooth] machine. I also have the new 4G SumUp machine. Out of all 3, I can say the iZettle machine is perfect in every way. It is very fast at taking payments from contactless. Almost instant. I have NEVER had a problem with it connecting to my phone, beit a Samsung Galaxy SS6, Hauwei P20 or my current phone iPhone XR. It connects, each and every time instantly without a complaint. The SumUp Bluetooth machine is, IMHO, not good. It will regularly disconnect from bluetooth, even right in the middle of a transaction. You cannot imagine how embarrassing that is when you have a customer wants to catch their train and they then have to go to the cash point machine. So annoying. It currently resides in a drawer somewhere. The [new] SumUp 3g machine is prone to problems too. The battery is awful. I mean literally awful. It will drain 20% per hour, without even thinking about it, and that is in "standby". Yes, in standby!!! That means, to save power, I have to turn it off in between transactions! Then, as I am approaching the destination I will turn it on and hope for the best. I quite often get "Connection error", and I even had a "blue screen" 3 times so far....like the old Windows bluescreen of Death (see pic below) I was even taking an £85 fare recently and it froze right as the card was inserted. This meant the passenger had to wait for a full reboot. (My iZettle was at home I forgot it) I just keep the SumUp 4g purely as a back up now. I wasted £60 odd quid on that one! If you want my honest recommendation, go for iZettle every time. It may be 0.25% more, but my God, it's worth it to save the embarrassment that is the SumUp machines. The new SumUp 4G Blue Screen of Death.
I’ve used SumUp for over 3 years. Very fast payouts, reader is quick to use.
How does it compare to Square or PayPal card readers in terms of charges and speed of payments arriving into one’s account? Anyone know?
