Quantity Change Plus and Minus slow on mobile

Hi There - I am putting together a responsive site using Hikashop - and on the product list which has around 300 to 400 products per page - the Up and Down (plus and minus) quantity changer is a bit too slow on an iPhone. On a desktop you can click it 10 times as fast as you can and it responds to all 10 clicks and changes the quantity in the input field to 11. But on a mobile - if you tap the up button numerous times it only responds to one tap and changes the quantity to 2. The way this site will be used is people will put large quantities of things in the cart (probably 5 or more items of probably 10 different products as a minimum) and they will be majority from a mobile - so I need to speed this up if possible.

I tried paginating the products and listing a maximum of 5 per page, this sped it up a little bit, but only marginally.

I am also not using any inventory on this site, so I tried removing the onchange listener on the input field that checks for the max and min quantities available for the product - this sped it up a little bit more, but again only marginally.

Even with these changes, you still have to wait nearly a second per click - I know that doesn't sound like much but I have given this to a few people to use and they all go to operate it the same way and tap the up arrow numerous times (5 for example) and it only adds one item to the count.

Thanks in advance for any help...

Hi,

In the next release there will be more options for the quantity display, one of them is a dropdown.
Will that not be more adapted for mobile ? The select on mobile is displayed depending on the os, and it will be more user friendly to select a quantity thanks to that.
