I've just downloaded this app and I find it great! anyway I would like to set the height of the logo a little smaller but it says not less than 20. I've contacted the support for more info.
EDIT: support contacted me right after this review and resolved the problem. GREAT!

Really good GG. Awesome app, definitely usefull if your customers uses whatsapp as a means of communication!

The app is excellent, both for the client who browses on the computer and on the smartphones. Simple to be installed and reliable. I recommend...

Awesome app. Easy to use. Definitely useful if your target customer base uses WhatsApp as a means of communication.

Ottima app, funziona bene e fa quello che dice. La versione gratis è sufficiente ma la versione a pagamento ha un prezzo accessibile ed è molto utile nel caso sia necessario utilizzare più numeri di telefono. Consigliata

This option looks great, lets see if it will help with the sales of our products on our online shop.

Perfeito, no plano free me satisfaz, espero um dia poder retribuir com o plano pago. Eu usava o messenger do Facebook e removi, esse é bem melhor.

Eu gostei muito, passa uma credibilidade legal pra loja, facilita a comunicação com o cliente, bom demais

The perfect app to engage with customers over Whatsapp. It's easy to configure and customize. I use it on all my stores.

I used this app to help our customer and I really like how this app help to chat with customer thanks for your support
